摘要
利用茂金属加合物和1种Zjegle-Natta(Z-N)催化剂的混合催化体系,制备宽/双峰分子量分布的聚乙烯。考察混合催化体系中茂金属加合物和Z-N催化剂的配比对聚合物分子量、分子量分布以及结构性能的影响。
The polyethylene resins with broad or bimodal molecular weight distribution was synthesized by use of the mixture of metallocene adduct (APE -1) and a kind of Zeigler - Natta (Z - N) catalyst. The effects of the ratio of APE - 1 to Z - N in the catalyst system on the molecular weight and its distribution, structure and properties of the polymer were studied in detail.
