【Abstract】 In this paper, the regularities of graft copolymerization of ethyl acrylate （EA）and corn starch using Ce⁴⁺ as initiator is reported. Our experimental results showed that the percent grafting （G%）and graft efficiency were considerably affected by Ce⁴⁺, EA, reaction temperature and time. The maximum G and E were obtained at 10～12m mol/l of Ce⁴⁺and 5～6d mol/l of EA at 40℃ in 3h.In this study, we found that S-G-PFA can be processed to give a film, it undergoes enzymatic degradation and the loss in weight is about 20% in 27 days.更多还原
