Hydrogel of poly (SSNa-cross-TeEGDMA): preparation, characterization, and Swelling behavior was written by Bradai, Masika;Ould Kada, Seghier;Sebba, Fatima Zohra;Sebti, Houari. And the article was included in Pharma Chemica in 2016.Formula: C16H26O7 This article mentions the following:
Series of novel hydrogels based on sodium styrene sulfonate(SSNa) and tetraethylene glycol dimethacrylate (TeEGDMA) copolymers, were prepared by free radical crosslinking copolymerization and were characterized using Spectra of Fourier transform IR spectroscopy (FTIR), and differential scanning calorimetry (DSC). The swelling properties of these hydrogels were achieved in distilled water at different pH at 25°C, the results showed that the swelling ratio are proportional to the sodium styrene sulfonate (SSNa) percent molar composition of 40, 50 and 80 incorporated in each hydrogel, The values swelling ratio of the basic medium are higher than those observed in acidic and neutral medium. 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: 109-17-1Formula: 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. 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.Formula: C16H26O7
