A series of propylene--styrenic monomer copolymers were synthesized using the Friedel⁻Crafts alkylation reaction between chlorinated PP and substituted benzene, and the effects of these copolymers on a PP/PS (80/20) blend were investigated by using the impact test, morphology observation, thermo- and dynamic mechanical analysis, and rheology measurements. The results showed that the compatibilization efficiency varied as the variation of the substitute on the benzene ring of the styrenic monomer unit was incorporated in the PP chain in an order of methyl > ethyl > methoxyl. The copolymers bearing a crystalline isotactic polypropylene chain sequence and rubbery propylene--styrene-like unit chain segments may prepossess imaginable applications, giving an example for the synthesis and applications of PP-based copolymers, initiating a new way to broaden the polyolefin-based material family.
通过氯化聚丙烯与取代苯之间的傅克烷基化反应合成了一系列丙烯 - 苯乙烯类单体共聚物，并通过冲击试验、形态观察、热分析和动态力学分析以及流变学测量研究了这些共聚物对PP/PS（80/20）共混物的影响。结果表明，随着苯乙烯类单体单元苯环上取代基的变化，其在PP链中的引入导致增容效率按甲基>乙基>甲氧基的顺序变化。带有结晶等规聚丙烯链序列和橡胶状丙烯 - 苯乙烯类单元链段的共聚物可能具有想象中的应用前景，为基于PP的共聚物的合成和应用提供了一个实例，开创了拓宽聚烯烃基材料家族的新途径。
