pH-Responsive Hydrogel with Controlled Swelling and Degradation Rate


A range of hydrogels were prepared by solution polymerization of methacrylic acid, poly(ethyleneglycol) methyl ether methacrylate (M.W. 475 g/mol) and poly(ethyleneglycol) dimethacrylate (as the cross-linking, M.W. 550 or 875 g/mol) in various proportions. The effects of methacrylic acid/ poly(ethyleneglycol) methyl ether methacylate concentration ratios as… (More)
