聚合物载体负载TiCl4/i-Bu3Al催化烯烃聚合

摘要

探讨了聚合物负载烯烃聚合催化剂的合成及用于聚合的研究.研究了聚合物作为载体的催化行为.并通过IR，DsC，元素分析和粘度法测定分子量等手段对催化剂及聚合物进行了表征.包括合成聚合物负载的Ti体系催化剂和用所合成的催化剂进行乙烯聚合，乙烯、丙烯与丁二烯共聚合的研究.%The polymer-supported TiC14 catalyst was synthesized and the catalytic features in the polymerization of ethylene and copolymerization of ethylene, propylene and butadiene in the presence of cocatalyst (Et3A1) were studied. The supported catalyst and obtained polymers were characterized by IR, DSC, elemental analysis and viscosity molecular weight measurements.
