摘要: Hydrogels are water-swollen, cross-linked polymeric structures. The objective of this study was to synthesize a new pH-sensitive copolymer, which shows no water uptake at lower pH values but maximum higher values. Methyl methacrylate-co-itaconic acid [P(MMA/ IA)] hydrogels with methylene bis-acrylamide were synthesized. To determine the effect monomeric composition, copolymers prepared different proportions methyl methacrylate and itaconic i.e. 100:0, 90:10, 85:15, 80:20 75:25 keeping degree cross-linking constant 0.30 mol %. It concluded from that MMA/IA (x = 0.3 mol %) polymer fulfilled our objective. seems suitable for delivering drug above pH 6.
