Biodegradable hydrogels have become a rapidly expanding area of research for biomedical applications. Poly(β-amino ester) (PBAE) biodegradable hydrogels, in particular, have been studied extensively because of the ease of synthesis and range of properties exhibited. In this work, PBAE macromers were created with poly(ethylene glycol) diacrylate (PEGDA), diethylene glycol diacrylate (DEGDA), and isobutylamine. Many methods have been presented that allow control over the resulting hydrogel behavior. Here, properties were varied by combining multiple diacrylate components in the macromer synthesis step (single macromer (SM)) or through the combination of multiple macromers prior to polymerization (double macromer (DM)). The exhibited properties are a result of the hydrophilic/hydrophobic contributions of the different diacrylate mols. to the macromer. The SM systems exhibited linear degradation profiles, the rate of degradation increased as the PEGDA concentration increased. DM systems exhibited a multiphase degradation profile as a result of the combination of macromers with different hydrophilic properties. In the experiment, the researchers used many compounds, for example, Diethyleneglycoldiacrylate (cas: 4074-88-8Safety of Diethyleneglycoldiacrylate).
Diethyleneglycoldiacrylate (cas: 4074-88-8) 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. Grignard and organolithium reagents are powerful tools for organic synthesis, and the most common products of their reactions are alcohols.Safety of Diethyleneglycoldiacrylate
