Group 3-6 or Lanthanide metal complexes possessing two metal centers joined by means of a divalent bridging group joining trivalent moieties comprising boron or a member of Group 14 of the Periodic Table of the Elements, and optionally also comprising nitrogen, phosphorus, sulfur or oxygen, in the complexes, catalysts derived therefrom by combining the same with strong Lewis acids, Bronsted acid salts, salts containing a cationic oxidizing agent or subjected to bulk electrolysis in the presence of compatible, inert non-coordinating anions and the use of such catalysts for polymerizing olefins, diolefins and/or acetylenically unsaturated monomers are disclosed.
本发明涉及一种拥有两个金属中心的第三至六族或镧系金属配合物,其通过双价桥接基团连接三价硼或元素周期表第14族的成员,以及在配合物中选择性地包含氮、磷、硫或氧,由此组成的催化剂。该催化剂通过与强路易斯酸、布朗斯特德酸盐、含有阳离子氧化剂的盐或在兼容的惰性非配位阴离子存在下进行大量电解而得到,用于聚合烯烃、二烯烃和/或炔基不饱和单体。
