    • The new metallocene catalysts according to the present invention are prepared by reacting a metallocene compound with a compound having at least two functional groups. The metallocene compound is a transition metal compound, which is coordinated with a main ligand such as cyclopentadienyl group, and an ancillary ligand. The functional groups in the compound are selected from the group consisting of a hydroxyl group, an alkyl or aryl magnesium halide, a thiol group, a primary amine group, a secondary amine group, a primary phosphorous group, a secondary phosphorous group, etc. The metallocene catalysts according to the present invention have a structure in which an ancillary ligand of a metallocene compound is bonded to the functional groups of a compound having at least two functional groups. A structure of the metallocene catalysts can be varied with the type of a metallocene compound and a compound having at least two functional groups, and the molar ratio of each reactant. The metallocene catalysts are employed with a co-catalyst for olefin polymerization. The co-catalyst is an organometallic compound, or a mixture of non-coordinated Lewis acid and alkylaluminium as it is well known in the art.
    • 根据本发明的新的茂金属催化剂通过茂金属化合物与具有至少两个官能团的化合物反应制备。 金属茂化合物是与主配体如环戊二烯基配位的过渡金属化合物和辅助配体。 化合物中的官能团选自羟基,烷基或芳基卤化镁,硫醇基,伯胺基,仲胺基,伯磷基,仲磷基等。 根据本发明的茂金属催化剂具有其中金属茂化合物的辅助配体与具有至少两个官能团的化合物的官能团结合的结构。 金属茂催化剂的结构可以随着金属茂化合物的类型和具有至少两个官能团的化合物和各反应物的摩尔比而变化。 茂金属催化剂与用于烯烃聚合的助催化剂一起使用。 助催化剂是有机金属化合物,或非配位路易斯酸和烷基铝的混合物,如本领域所熟知的。
