Synthesis, characterization, and enzymatic degradation of starch-grafted poly(methyl methacrylate) copolymer films

Graft copolymerization of methyl methacrylate (MMA) onto the corn starch (CS) backbone was carried out in an aqueous medium using ceric ammonium nitrate as an initiator under nitrogen atmosphere. The weight ratio of CS/MMA varied with their composition, as 7/3, 6/4, 5/5, 4/6, and 3/7 were used in this study of the graft efficiency and graft percentage (GP); thus, five different GP CS‐ g ‐PMMA copolymers were obtained. The molecular weight of CS‐...
