摘　　要：合成了丙烯酰氧基淀粉和以甲基丙烯酸羟乙酯为功能端基的聚乳酸大单体。研究了以丙烯酰氧基淀粉为母体的接枝共聚反应。制备了具有高接枝效率及单体转化率的淀粉 -醋酸乙烯酯接枝共聚物。Acryloyloxystarch was prepared and used as the parent for free radical initiated graft copolymerization with the end functionalized hydroxyethyl methacrylate macromonomer of poly (D, L lactide). When 2,2′ azobisisobutyronitrile (AIBN) was used as the initiator, PLA macromonomers was successively grafted onto the modified starch. In contrast, no sign indicated that the macromonomer was grafted onto the original starch when the ceric salt was used as redox initiating system.
