摘要
均相催化剂产生于５０年代末期，但由于活性很低而未引起重视，８０年代初，由于发现ＭＡＯ具有良好的助催化能力而使均相催化剂得到了很大发展，涌现了多种催化体系，广泛地使α－烯烃及其衍生物立体选择性聚合，开辟了配位聚合研究的新领域。本文对均相催化剂的产生、发展及现状作了综合评述。
Homogeneous Ziegler-Natta catalysts have been known since 1950s, but they have very low activities at that time.In 1980, it was found that using of oligomeric methylaluminoxane(MAO)as cocatalyst significantly increase the activity of the catalysts. The discovery made Ziegler-Natta catalysts in a state of renaissance and many new catalyst systems appear which can stereoselectively polymerize α-olefins and their derives. In this paper we present a review on the formation and development of homogeneous Ziegler-Natta catalysts.
