合成了具有半二茂锆结构的氧化铝苯-烷基锆配合物。该配合物的 X 射线晶体分析揭示了由阳离子烷基氯化锆和四配位铝酸盐组成的两性离子结构。在催化量的这种络合物的存在下，乙烯聚合可以在没有任何添加剂的情况下进行，形成超高分子量聚乙烯。
An aluminabenzene–alkylzirconium complex having a half-zirconocene structure was synthesized. X-ray crystallographic analysis of this complex revealed a zwitterionic structure consisting of cationic alkylzirconium chloride and four-coordinated aluminate. In the presence of a catalytic amount of this complex, ethylene polymerization could proceed without any additives to form ultra-high molecular weight polyethylene.
