| 摘 要： | 以丙烯酸丁酯（BA）、马来酸酐（MAH）和苯乙烯（St）为接枝单体，偶氮二异丁腈（AIBN）为引发剂，加入少量有机溶剂作分散剂，对聚丙烯进行固相接枝改性制备接枝共聚物。考察了反应时间、反应温度、引发剂用量等因素对接枝反应的影响，用红外光谱对接枝产物进行了表征。结果表明，当引发剂用量（以PP质量为基准）为0．3％，单体（n（BA）：n（St）：n（MAH）=2：1：1）总投料量为4％时，得到了接枝率为3．26％的接枝产品。单体利用率达到70％。

| Abstract: | Grafted PP was prepared by radical polymerization in solid-phase, using AIBN as initiator, and an organic liquid as dispersing agent. Butyl acrylate （BA）, maleic anhydride （MAH） and styrene （St） were employed as monomers for copolymerization. The effects of reaction parameters such as reaction time, reaction temperature, initiator dosage were studied. The grafted product was characterized by FTIR. The product with the max. of grafting rate of 3.26% was obtained when the dosage of initiator was 0.3% based on PP, monomers （n（BA）：n（St）：n（MAH）=2：1：1）, total dosage was 4%.Monomer utilization rate was 70% |
