摘要
乙烯在一个反应器中同时进行均聚和共聚反应的新工艺,是近年来乙烯聚合研究领域中的热点之一。本文以混合型有机铬/氧化铬催化剂和钛系催化剂为例,介绍了乙烯聚合双功能催化剂的制备方法、技术特点、聚合动力学以及所合成树脂的性能等,综述了该研究领域的一些新进展,并对两种不同类型的双功能催化剂进行了简单评述。
The new process for the simultaneous oligomerization and copolymerization of ethylene in a single reactor is a focus of ethylene polymerization research in recent years The present paper reviewed the advences of dual functional catalysts for ethylene polymerization that based on chromium catalyst systems and titanium catalyst systems, and described briefly the ffeatures of dual ffunctional catalysts。
