摘　　要：以甲苯为溶剂,过氧化二苯甲酰(BPO)为引发剂,通过自由基聚合,采用醋酸乙烯酯(VAc)接枝改性氯化聚丙烯(CPP);研究了不同反应温度、反应时间、VAc的加入量和BPO的加入量对改性CPP粘接性能的影响;得出较佳的工艺条件为:反应温度T=85℃,反应时间t=2.0 h,反应物料的质量比m(CPP):m(VAc):m(BPO)=100:2.5:0.25。Grafting of vinyl acetate on chlorinated polypropylene by free radical process was carried out by using toluence as solvent and benzoperoxide as initiator ; 100 g polypropylene was added ;effects of different reaction temperature in 70℃ ,75℃,80 ℃ ,85℃,90 ℃, different reaction time in0. 5h,1. Oh,1. 5 ht 2. 0 h ,2. 5 h, different mass of VAc 1. 0 g, 1. 5 g,2. 0 g,2. 5 g ,3. 0 g and different mass of BPO 0. 10g, 0. 15 g,0. 20g,0. 25 g,0. 3 g on adhesion property were studied; the optimization process conditions is obtained as the following reaction temperature T=85 ℃, reaction time t = 2. 0 h, and mass ratio m(CPP) :m(VAc) : m(BPO) = 100 : 2.5 : 0.25
