摘    要:采用多元Flory分布函数对Cp2ZrCl2/异丁基铝氧烷和甲基铝氧烷制备的聚乙烯的GPC曲线进行了拟合,获得了很好的结果;表明在茂金属均相催化体系中存在多种活性中心,活性中心的金属原子与烷基中不同的氢原子的相互作用是形成多种活性中心的原因。

关 键 词:茂金属  聚乙烯  相对分子质量分布

Abstract:The complex GPC data of polyethylene synthesized by Cp 2ZrCl 2/IBAO and MAO is resolved into their constituents with Flory Schulz function using computer analysis The fitting result demonstrates that there is more than one type of active species in the metallocene catalyst system It is proposed that the formation of different active species can be due to the interaction between the center metal atom and the hydrogen atoms of alkyl
Keywords:metallocene  catalysts  polyethylene  molecular  weight  distribution
