Abstract: 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.
