摘　　要：以过氧化苯甲酰(BPO)为引发剂,用熔融接枝共聚法制备了聚己内酯接枝马来酸酐(PCL-g-MAH),探讨了PCL-g-MAH对热塑性淀粉(TPS)/聚己内酯(PCL)共混物增容作用、力学性能、耐水性能及生物降解性能等的影响。结果表明:加入适量的PCL-g-MAH后,共混物的耐水性和熔体流动速率提高;PCL-g-MAH用量为5份时,共混物的力学性能最佳;PCL-g-MAH的加入对共混物的生物降解性能没有明显影响。Taking BPO as initiator,PCL-g-MAH was prepared by melt grafting.The effects of PCL-g-MAH on compatibilization,mechanical property,water-resistance,biodegradable property,and etc.,of thermal plastic starch（TPS）/PCL blend were studied.The results show that：the addition of proper amount of PCL-g-MAH improves the water-resistance and flow ability,when PCL-g-MAH content is 5 phr,the mechanical property of the blend is the best;the addition of PCL-g-MAH has no obvious effect on biodegradable property of the blend.
