1,2-Diketones as photoinitiators of both cationic and free-radical photopolymerization under UV (392 nm) or Blue (455 nm) LEDs was written by Zhang, Jing;Wang, Shuhui;Lalevee, Jacques;Morlet-Savary, Fabrice;Lam, Elizabeth S.-H.;Graff, Bernadette;Liu, Jing;Xing, Feiyue;Xiao, Pu. And the article was included in Journal of Polymer Science (Hoboken, NJ, United States) in 2020.Application In Synthesis of ((Oxybis(ethane-2,1-diyl))bis(oxy))bis(ethane-2,1-diyl) bis(2-methylacrylate) This article mentions the following:

The photoinitiation abilities of three 1,2-diketones [i.e., acenaphthenequinone (ANPQ), aceanthrenequinone (AATQ), and 9,10-phenanthrenequinone (PANQ)]-based photoinitiating systems [PISs, with additives such as iodonium salt, N-vinylcarbazole (NVK), tertiary amine, and phenacyl bromide (R-Br)] for cationic photopolymerization and free-radical photopolymerization under the irradiation of UV (UV; 392 nm) or blue (455 nm) light-emitting diode (LED) bulb are investigated. All 1,2-diketones studied exhibit ground state absorption that match with the emission spectra of UV (392 nm) or blue LED (455 nm) better than that of the well-known blue-light-sensitive photoinitiator camphorquinone (CQ). In particular, AATQ/iodonium salt/NVK can show high photoinitiating ability (with epoxide conversion yield >70%) under the UV light irradiation due to the effect of NVK. In addition, 1,2-diketone/iodonium salt (and optional NVK) systems are capable of initiating free-radical photopolymerization of methacrylates, with conversions of 50-58%. Furthermore, some 1,2-diketone/tertiary amine (and optional R-Br) combinations are found to demonstrate high efficiency to initiate free-radical photopolymerization, and 71% of methacrylate conversion can be achieved with PANQ/tertiary amine/R-Br PIS. Some 1,2-ketone-based PISs can even exhibit higher efficiency than the CQ-based systems. The photochem. mechanism of the radical generation from the 1,2-diketone-based PISs is investigated and consistent with the related photopolymerization efficiency. In the experiment, the researchers used many compounds, for example, ((Oxybis(ethane-2,1-diyl))bis(oxy))bis(ethane-2,1-diyl) bis(2-methylacrylate) (cas: 109-17-1Application In Synthesis of ((Oxybis(ethane-2,1-diyl))bis(oxy))bis(ethane-2,1-diyl) bis(2-methylacrylate)).

((Oxybis(ethane-2,1-diyl))bis(oxy))bis(ethane-2,1-diyl) bis(2-methylacrylate) (cas: 109-17-1) belongs to alcohols. Alcohols are weak acids. The most acidic simple alcohols (methanol and ethanol) are about as acidic as water, and most other alcohols are somewhat less acidic. Converting an alcohol to an alkene requires removal of the hydroxyl group and a hydrogen atom on the neighbouring carbon atom. Dehydrations are most commonly carried out by warming the alcohol in the presence of a strong dehydrating acid, such as concentrated sulfuric acid.Application In Synthesis of ((Oxybis(ethane-2,1-diyl))bis(oxy))bis(ethane-2,1-diyl) bis(2-methylacrylate)

Meta-Terphenyls as versatile fluorescent molecular sensors for monitoring the progress of hybrid polymerization processes was written by Tomal, Wiktoria;Szymaszek, Patryk;Bilut, Magdalena;Popielarz, Roman;Swiergosz, Tomasz;Ortyl, Joanna. And the article was included in Polymer Chemistry in 2022.Electric Literature of C16H26O7 This article mentions the following:

Herein, the performance of a series of 2-amino-4,6-diphenylbenzene-1,3-dicarbonitrile derivatives in the role of fluorescent mol. sensors for monitoring progress of various photopolymerization processes by the Fluorescence Probe Technique (FPT) has been evaluated. It was found that all of the derivatives studied, except for the one containing a nitro substituent in its structure, showed high enough sensitivity and stability to be applied as versatile sensors for both cationic and free-radical polymerization processes. Next, the applicability of the sensors was applied for study of hybrid polymerization processes (i.e., both cationic and free radical polymerization reactions occurring simultaneously). The hybrid photopolymerization of pure glycidyl methacrylate (GlyMA) and the mixtures of GlyMA with 3,4-epoxycyclohexylmethyl 3,4-epoxy-cyclohexanecarboxylate (CADE), or CADE with trimethylolpropane triacrylate (TMPTA) was studied. It was found that during the hybrid photopolymerization of CADE/TMPTA mixtures, each monomer polymerized independently to form an interpenetrated polymer network (IPN). On the other hand, hybrid photopolymerization of GlyMA/CADE mixtures leads to a copolymer, where final functional group conversions are higher than those achievable by the corresponding photopolymerizations of pure GlyMA and CADE monomers. The use of m-terphenyl sensors allows for real-time monitoring of various hybrid polymerization processes and provides key information on the processes, which was not previously possible. In the experiment, the researchers used many compounds, for example, ((Oxybis(ethane-2,1-diyl))bis(oxy))bis(ethane-2,1-diyl) bis(2-methylacrylate) (cas: 109-17-1Electric Literature of C16H26O7).

((Oxybis(ethane-2,1-diyl))bis(oxy))bis(ethane-2,1-diyl) bis(2-methylacrylate) (cas: 109-17-1) belongs to alcohols. The oxygen atom of the strongly polarized O鈥旽 bond of an alcohol pulls electron density away from the hydrogen atom. This polarized hydrogen, which bears a partial positive charge, can form a hydrogen bond with a pair of nonbonding electrons on another oxygen atom. Under carefully controlled conditions, simple alcohols can undergo intermolecular dehydration to give ethers. This reaction is effective only with methanol, ethanol, and other simple primary alcohols.Electric Literature of C16H26O7

Hydrogels have potential applications as sustained-release drug delivery systems, as an example in treatment of major depressive disorders. This paper reports some works carried out to obtain a new type of copolymeric hydrogel for an anti-depressant drug. The copolymerization of itaconic acid, hydroxyethyl methacrylate (HEMA), and tetraethyleneglycol dimethacrylate was performed. The gels were evaluated for swelling, diffusion coefficient, drug incorporation, in vitro dissolution, and in vivo performance in rabbits after oral administration. The pharmacokinetic parameters like bioavailability, C_max and T_max were calculated for hydrogels in comparison to oral solution containing equivalent amount of venlafaxine. The HEMA-based matrixes showed negligible swelling and release rate of venlafaxine, which were also very low in a buffer of pH 1.2. However, both the swelling and release rate of venlafaxine were faster at high pH (6.5 and 7.5). The T_max of the formulation with the highest swelling and release rate (T₁) were found at 600 min compared to that at 180 min for oral solution having equivalent quantity of venlafaxine. However, C_max for oral cross-linked hydrogel composite was significantly lower than that for equivalent amount of oral drug solution The synthesized hydrogel composites showed a promising ability for sustained release of venlafaxine both in vitro and in vivo. It was found that venlafaxine delivery through oral route was practical. In the experiment, the researchers used many compounds, for example, ((Oxybis(ethane-2,1-diyl))bis(oxy))bis(ethane-2,1-diyl) bis(2-methylacrylate) (cas: 109-17-1Name: ((Oxybis(ethane-2,1-diyl))bis(oxy))bis(ethane-2,1-diyl) bis(2-methylacrylate)).

Under appropriate conditions, inorganic acids also react with alcohols to form esters. To form these esters, a wide variety of specialized reagents and conditions can be used. Secondary alcohols are easily oxidized without breaking carbon-carbon bonds only as far as the ketone stage. No further oxidation is seen except under very stringent conditions.Name: ((Oxybis(ethane-2,1-diyl))bis(oxy))bis(ethane-2,1-diyl) bis(2-methylacrylate)

Fractography of poly(N-isopropylacrylamide) hydrogel networks crosslinked with mechanofluorophores using confocal laser scanning microscopy was written by Stratigaki, Maria;Baumann, Christoph;van Breemen, Lambert C. A.;Heuts, Johan P. A.;Sijbesma, Rint P.;Goestl, Robert. And the article was included in Polymer Chemistry in 2020.SDS of cas: 109-17-1 This article mentions the following:

Due to their soft and brittle nature, the mech. characterization of polymer hydrogels is a difficult task employing traditional testing equipment. This paper studies poly(N-iso-Pr acrylamide) (PNIPAAm) hydrogel networks with Diels-Alder adducts of 蟺-extended anthracenes as mechanofluorophore crosslinkers. After swelling the networks with varying amounts of water and subjecting them to force, the subsequent fluorescence caused by covalent bond scission is visualized with confocal laser scanning microscopy (CLSM) and the intensities is related to the macroscopic fracture mechanics and the elastic moduli recorded with traditional uniaxial compression. The sensitivity of the mechanofluorophores allowed the anal. of low levels of mech. stress produced through a hand-induced needle-puncturing process and, thus, is an alternative to conventional force application methods. The detection and precise localization of covalent bond scission through CLSM helps elucidating the interrelationship between mol. structure and the macroscopic properties of chem. crosslinked polymeric hydrogels. The micro-scale mechanophore-assisted fractog. can establish a new paradigm for the mech. anal. of soft matter in fields covering traditional polymer and life sciences.

Photopolymerizable nanogels as macromolecular precursors to covalently crosslinked water-based networks was written by Dailing, Eric A.;Setterberg, Whitney K.;Shah, Parag K.;Stansbury, Jeffrey W.. And the article was included in Soft Matter in 2015.Related Products of 109-17-1 This article mentions the following:

We present a strategy for directly and efficiently polymerizing aqueous dispersions of reactive nanogels into covalently crosslinked polymer networks with properties that are determined by the initial chem. and phys. nanogel structure. This technique can extend the range of achievable properties and architectures for networks formed in solution, particularly in water where monomer selection for direct polymerization and the final network properties are quite limited. Nanogels were initially obtained from a solution polymerization of a hydrophilic monomethacrylate and either a hydrophilic PEG-based dimethacrylate or a more hydrophobic urethane dimethacrylate, which produced globular particles with diameters of 10-15 nm with remarkably low polydispersity in some cases. Networks derived from a single type of nanogel or a blend of nanogels with different chemistries when dispersed in water gelled within minutes when exposed to low intensity UV light. Modifying the nanogel structure changes both covalent and non-covalent secondary interactions in the crosslinked networks and reveals critical design criteria for the development of networks from highly internally branched, nanoscale prepolymer precursors. In the experiment, the researchers used many compounds, for example, ((Oxybis(ethane-2,1-diyl))bis(oxy))bis(ethane-2,1-diyl) bis(2-methylacrylate) (cas: 109-17-1Related Products of 109-17-1).

Polymer-Network Toughening and Highly Sensitive Mechanochromism via a Dynamic Covalent Mechanophore and a Multinetwork Strategy was written by Watabe, Takuma;Aoki, Daisuke;Otsuka, Hideyuki. And the article was included in Macromolecules (Washington, DC, United States) in 2022.Application In Synthesis of ((Oxybis(ethane-2,1-diyl))bis(oxy))bis(ethane-2,1-diyl) bis(2-methylacrylate) This article mentions the following:

Multinetwork (MN) elastomers exhibit outstanding mech. properties that arise from the sacrificial first network (FN). Here, we report the mech. and mechanochromic properties of an MN elastomer with a difluorenylsuccinonitrile (DFSN) moiety incorporated into the crosslinking points of its FN. DFSN is a mechanochromophore that affords stable, pink radical intermediates upon exposure to mech. stimuli. We distinctly demonstrated that the replacement of a conventional cross-linker by a weaker cross-linker does have a direct effect on the stress-strain behavior of elastomers to improve fracture toughness. The toughening mechanism of the DFSN-containing MN elastomers was revealed through a highly sensitive and quant. anal. of the mech. activated stable radicals by ESR spectroscopy. We also clarified that the MN strategy is an effective technique to achieve high activation of the mechanophores at a lower threshold strain.

Poly(Hydroxypropyl methacrylate-co-glycidyl methacrylate): Facile synthesis of well-defined hydrophobic gels containing hydroxy-functional methacrylates was written by Orakdogen, Nermin;Sanay, Berran. And the article was included in Polymer Degradation and Stability in 2017.Synthetic Route of C16H26O7 This article mentions the following:

A range of well-defined hydrophobic hydroxy-functional methacrylate-based gels has been synthesized by free-radical crosslinking copolymerization of the monomers Hydroxypropyl methacrylate (HPMA) and Glycidyl methacrylate (GMA). Particularly, the effect of the hydrophobic functional groups of the comonomer GMA on the elasticity and swelling properties was investigated in order to understand the exact interactions and the consequent changes in the phys. characteristics of poly(Hydroxypropyl methacrylate-co-glycidyl methacrylate) P(HPMA-co-GMA) hydrogels as well as cryogels. In addition, measuring and understanding how to control the mech. response of the resulting gels which usually refers to the resistance to failure by fracture or excessive deformation can help the targeted design of specific applications with extended functionality. In the light of the exptl. findings, it was suggested that the studied system with the monomers HPMA and GMA containing both acrylic and epoxy groups provides the design and performance versatility required for the most demanding coating and resin applications. In the experiment, the researchers used many compounds, for example, ((Oxybis(ethane-2,1-diyl))bis(oxy))bis(ethane-2,1-diyl) bis(2-methylacrylate) (cas: 109-17-1Synthetic Route of C16H26O7).

Antistaphylococcal and biofilm inhibitory activities of Frangula alnus bark ethyl-acetate extract was written by Djukanovic, Stefana;Cvetkovic, Stefana;Loncarevic, Branka;Ljesevic, Marija;Nikolic, Biljana;Simin, Natasa;Bekvalac, Kristina;Kekic, Dusan;Mitic-Culafic, Dragana. And the article was included in Industrial Crops and Products in 2020.Computed Properties of C16H26O7 This article mentions the following:

Since that we are facing with a serious problem of bacterial resistance it is necessary to find a new antibacterial agents in fight with it. Frangula alnus is traditionally used plant but its antibiofilm potential is poorly investigated. The aim of the study was to investigate antibiofilm activity of F. alnus ethyl-acetate extract (FA) toward S. aureus ATCC strains and clin. isolates as well as its influence on respiration in planktonic and biofilm form. The qual. GCxGC-MS and quant. LC-MS/MS anal. revealed that FA extract was rich in phenols and flavonoids and emodin, chatechin, and ester 4-ethoxy benzoic acid were the most dominant components. Results obtained through microdillution assay showed that FA possesses strong antibacterial activity. Furthermore, crystal violet staining of biofilm biomass demonstrated that extract had strong effect on biofilm formation of all tested strains while effect on preformed biofilms was less pronounced. The effect on biofilm was confirmed with SEM where the changes in biofilm structure were noticed. The activity of extract on the consumption of O2 and production of CO2 was monitored using the Micro-Oxymax respirometer. Interestingly, respiration of the most strains was decreased in planktonic form as well as in biofilms. Results obtained in this study are a good basis for further research in order to discover the mechanism of action of the FA extract on connection between biofilm and respiration. In the experiment, the researchers used many compounds, for example, ((Oxybis(ethane-2,1-diyl))bis(oxy))bis(ethane-2,1-diyl) bis(2-methylacrylate) (cas: 109-17-1Computed Properties of C16H26O7).

Differences in molecular structure in cross-linked polycationic nanoparticles synthesized using ARGET ATRP or UV-initiated polymerization was written by Forbes, D. C.;Peppas, N. A.. And the article was included in Polymer in 2013.Related Products of 109-17-1 This article mentions the following:

This work compares material properties of polycationic nanoparticles synthesized using the techniques of UV-initiated polymerization or ARGET ATRP and relates differences in material properties to differences in mol. structure. The nanoparticles are based on the pH-responsive monomer 2-(diethylamino)ethyl methacrylate (DEAEMA) copolymerized with poly(ethylene glycol) Me ether methacrylate (PEGMA), tert-Bu methacrylate (tBMA), and tetraethylene glycol dimethacrylate (TEGDMA) in a surfactant-stabilized monomer-in-water emulsion to form cross-linked nanoscale hydrogels. ARGET ATRP resulted in a narrower distribution of mol. weight for linear analogs of the polycationic nanoparticles. In addition, ARGET ATRP formulations showed a sharper glass transition than UV-initiated formulations, indicating increased homogeneity. These networks could be used as drug delivery carriers or for other nanogel applications that would benefit from polycationic nanoparticles with high homogeneity.

It was found that during the hybrid photopolymerization of CADE/TMPTA mixtures, each monomer polymerized independently to form an interpenetrated polymer network (IPN).
