Effect of type and concentration of nanoclay on the mechanical and physicochemical properties of bis- GMA/TTEGDMA dental resins was written by Encalada-Alayola, J. J.;Veranes-Pantoja, Y.;Uribe-Calderon, J. A.;Cauich-Rodriguez, J. V.;Cervantes-Uc, J. M.. And the article was included in Polymers (Basel, Switzerland) in 2020.Electric Literature of C16H26O7 This article mentions the following:
Bis-GMA/TTEGDMA-based resin composites were prepared with two different types of nanoclays: an organically modified laminar clay (Cloisite 30B, montmorillonite, MMT) and a microfibrous clay (palygorskite, PLG). Their physicochem. and mech. properties were then determined Both MMT and PLG nanoclays were added into monomer mixture (1:1 ratio) at different loading levels (0, 2, 4, 6, 8 and 10 weight%), and the resulting composites were characterized by SEM (SEM), thermogravimetric anal. (TGA), dynamic mech. anal. (DMA) and mech. testing (bending and compressive properties). Thermal properties, depth of cure and water absorption were not greatly affected by the type of nanoclay, while the mech. properties of dental resin composites depended on both the variety and concentration of nanoclay. In this regard, composites containing MMT displayed higher mech. strength (both flexural and compression) than those resins prepared with PLG due to a poor nanoclay dispersion as revealed by SEM. Solubility of the composites was dependent not only on nanoclay-type but also the mineral concentration Dental composites fulfilled the min. depth cure and solubility criteria set by the ISO 4049 standard In contrast, the min. bending strength (50 MPa) established by the international standard was only satisfied by the dental resins containing MMT. Based on these results, composites containing either MMT or PLG are potentially suitable for use in dental restorative resins, although those prepared with MMT displayed better results. 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. 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. A multistep synthesis may use Grignard-like reactions to form an alcohol with the desired carbon structure, followed by reactions to convert the hydroxyl group of the alcohol to the desired functionality.Electric Literature of C16H26O7
