摘　　要：介绍利用茂金属催化剂与Ziegler-Natta催化剂、茂金属催化剂与氧化铬催化剂混合或者2种单组分茂金属催化剂复配获得的复合催化剂。该复合催化剂在单反应器聚合工艺条件下可产出宽分布或双峰分布的茂金属聚乙烯产品来改善其加工性能。The hybrid catalysts such as mixtures of metallocene catalyst combined with Ziegler-Natta or chromium oxide catalysts, or two kinds of single metallocene catalyst were described. Broad or bimodal distribution polyethylene product with metallocene-related catalyst could be obtained under condition of the single reactor polymerization process;processability performance of the polyethylene product was improved.

关 键 词：茂金属复合催化剂 聚乙烯 加工性能
