摘　　要：综述了乙烯原位共聚法制备线性低密度聚乙烯研究的新进展。按照齐聚催化剂的类型,分别介绍了二聚催化体系、宽分布乙烯齐聚催化体系、三聚催化体系及四聚催化体系,并对共聚催化剂作了简要说明。提出了乙烯原位共聚的发展方向。The advances in preparation of LLDPE by in situ polymerization of ethylene were reviewed. According to the type of oligomerization catalysts, dimerization, trimerization, and tetramerization catalyst systems and oligomerization catalysts system for wide range oligomer were introduced respectively. The copolymerization catalysts were presented briefly. The development direction of ethylene in situ copolymerization was proposed.
