摘　　要：系统介绍了国内外用于单反应器法生产宽/双峰聚乙烯的催化剂,主要包括混合催化剂、双/多金属催化剂、双载体催化剂和其它催化剂体系;阐述了各类催化体系的优缺点及研究现状;评述了各种催化剂的工业化应用前景。The catalysts used to produce broad/bimodal molecular weight distribution PE at home and abroad in a single reactor are introduced in this paper. They are mainly hybrid catalysts, bimetallic/ multimetallic catalysts, double supported catalysts and others. The advantages and disadvantages of the catalyst systems are reviewed. The industrial applications of such catalysts are prospected.
