水相法氯化聚丙烯用马来酸酐接枝改性与性能研究

摘要

以氯仿为溶剂,偶氮二异丁腈(AIBN)为引发剂,马来酸酐(MAH)为接枝单体,对氯化聚丙烯(CPP)进行接枝改性.优化的工艺条件为:m(AIBN)∶m(CPP) =0.003,m(MAH)∶m(CPP) =0.09,反应温度为108℃,反应时间为2.0h,接枝效率最高.改性产物在部分酮酯类溶剂中的溶解性能优良,对多种塑料材料有良好的附着性.%The chlorinated polypropylene (CPP) was grafted with chloroform as solvent,azobisisobutyroni-trile(AIBN) as initiator and maleic anhydride (MAH) as grafting monomer. The optimum technological conditions:m(AIBN) :m(CPP) = 0. 003,m(MAH) :m(CPP) = 0. 09,reaction temperature 108℃ and reaction time 2.0 h,the graft ratio would be the maximum. The grafted products have good solubility in some ketone or ester solvents,and have excellent adhesiveness on several plastic materials.
