一系列苯基取代的环戊二烯配体在甲苯中相继与丁基锂及ZrCl4作用,生成相 应的苯基取代的茂金属化合物,通过^1H NMR,MS和元素分析表征了化合物的分子 结构,并研究了在MAO(甲基铝氧烷的助催化下,化合物对乙烯聚合的催化性能, 结果发现单苯基取代茂金属化合物的催化活性和产物聚乙聚的分子量都随聚合温度 的升高而增大。

A series of phenyl- substituted cyclopentadienyl zirconocenes have been prepared by the reaction of the corresponding ligand with n-BuLi and ZrCL-4in toluene, which were characterized by 'H NMR, MS spectra and elemental analysis. Ethylene polymerizations with these complexes in combination with MAO were studied. It is found that the catalytic activity and the molecular weight of polyethylene with one phenyl substituted zirconocene increase with the enhancement of polymerization temperature.
