摘要：

In order to achieve new biocompatible materials, graft copolymerization of mixtures of hydroxyethyl methacrylate/ethyl acrylate (HEMA/EA) and hydroxypropyl methacrylate/ethyl acrylate (HPMA/EA) onto amylopectin by ceric ammonium nitrate initiation was carried out. The influence of feed composition was studied with respect to the characteristic grafting reaction yields. Homopolymer formation decreases as the per cent of HEMA monomer increases in the feed and increases as the per cent of HPMA monomer increases in the feed. The values obtained for the percentage grafting were quite high for all the feed compositions.
