摘要
研究了不同聚合条件下载体茂金属催化剂Et[Ind] 2 ZrCl2 -MAO/SiO2 的乙烯和丙烯共聚合活性、聚合物中丙烯含量以及聚合物的相对分子质量及其分布 ,实验结果表明 ,使用载体茂金属催化剂可以降低铝锆比而不会降低聚合活性。用1
The supported Et 2ZrCl 2-MAO/SiO 2 metallocene catalyst was used for the copolymerization of ethylene and propylene.The relationship between the condition of copolymerization and catalytic activity and polymer properties was studied.The structure of polymer was investigated with 13 C NMR.With Et 2ZrCl 2-MAO on SiO 2 the Al/Zr ratio of catalyst was reduced without decreasing catalytic activity.
