HPLC of Formula: 110-03-2In 2019, Bhaladhare, Sachin;Kim, Soeun;Carter, Kenneth R. published 《Mechanical Properties and Moisture Transport Behavior of Acid-Sensitive Hydrogels》. 《ACS Applied Polymer Materials》published the findings. The article contains the following contents:
Thin hydrogel films containing the acid sensitive cross-linker 2,5-dimethyl-2,5-hexanediol dimethacrylate (DHDMA) were synthesized as part of a larger project to create protective layers against chem. and biol. (CB) threats. In order to operate efficiently as fabric coatings, the mech. and moisture vapor transport properties of these materials must be understood. The hydrogels were composed primarily of poly(ethylene glycol) dimethacrylate (PEGDMA) and 2-hydroxyethyl methacrylate (HEMA) and were prepared by free radical crosslinking polymerization The influence of different compositions of DHDMA, PEGDMA, and HEMA on the moisture vapor transmission rate (MVTR), mech. properties, and swelling properties of PEGDMA/DHDMA/HEMA copolymer hydrogels has been investigated. The characterization by Fourier transform IR (FTIR) spectroscopy confirmed the presence of all monomers used in the gel structure. The hydrogels showed high MVTR, which are comparable to the widely accepted breathable membrane of Gore-Tex fabric and expanded polytetrafluoroethylene (ePTFE). The swelling data indicated that the equilibrium water content depends on the composition of hydrogels. It was found that addition of HEMA into the PEGDMA-based hydrogels was very helpful to improve the swelling properties but decrease in water contact angle. Rheol. study of hydrogels showed that the hydrogels are very stiff and their stiffness increases with increasing PEGDMA content in the hydrogels. And 2,5-Dimethyl-2,5-hexanediol (cas: 110-03-2) was used in the research process.
2,5-Dimethyl-2,5-hexanediol(cas:110-03-2) on heteropoly acid catalyzed dehydration yields cyclic ethers via stereospecific intramolecular SN2 mechanism. It reacts with nitriles in concentrated sulfuric acid to yield Δ1-pyrrolines.HPLC of Formula: 110-03-2
