The representative complexes Co2 and Co3 were confirmed by single crystal X-ray diffraction analyses, indicating pseudo-square-pyramidal geometry around the cobalt centre. All cobalt complexes,activated with either methylaluminoxane(MAO) or modified methylaluminoxane(MMAO), exhibited high activities towards ethylene polymerization, and produced polyethylenes with high molecular weight and highly linear feature as well as unimodal distribution. 关键词：线性聚乙烯乙烯聚合氯化物乙基合成 X-射线衍射分析甲基铝氧烷催化
