【摘要】 以甲苯为溶剂,过氧化二苯甲酰(BPO)为引发剂,采用甲基丙烯酸羟乙酯(HEMA)通过自由基聚合接枝对氯化聚丙烯(CPP)进行了改性。研究了反应温度、反应时间、引发剂用量、单体用量对氯化聚丙烯改性胶粘剂粘接性能的影响,并对接枝产物进行了FTIR表征,确定出较理想的工艺条件为反应温度θ=110℃,反应时间t=4h,m(CPP):m(HEMA):m(BPO)=1:1:0.1。更多还原

【Abstract】 s:Chlorinated polypropylene grafted by hydroxylethyl methacrylate was prepared by free radical processs in presence of toluence as solvent and benzoperoxide as initiator.The influence of reaction temperature, reaction time and dosage of HEMA and BPO on adhesion property were studied and the product was characterized with FTIR. Optimized reaction conditions were defermined as reaction temperature T=110℃, reaction time t=4h and mass ratio m(CPP):m(HEMA):m(BPO)=1:1:0.1.更多还原
