    • The present invention relates to a process for preparing a highly active metallocene catalyst supported on polymer bead for olefin polymerization, a metallocene catalyst prepared by the said process and a method for alkylene polymerization by employing the said catalyst. The process for preparing a highly active metallocene catalyst supported on polymer bead for olefin polymerization which comprises the steps of: dissolving divinylbenzene, vinylbenzylchloride, and an initiator in an organic solvent, mixing it with a suspension stabilizer of aqueous phase, and carrying out suspension-polymerization at the temperature of 40 to 80° C. to obtain polystyrene; swelling the polystyrene in dialcoholamine dissolved in an organic solvent at ambient temperature for 1 to 3 days, to give a polymer having a functional group of dialcoholamine; and, reacting the polymer with a metallocene compound (CpM*Cl3) dissolved in an organic solvent. The metallocene catalyst of the present invention can be used widely for ethylene polymerization, styrene polymerization and copolymerization, while replacing the conventional homogeneous catalysts.
    • 本发明涉及一种负载在用于烯烃聚合的聚合物珠上的高活性茂金属催化剂的方法,通过所述方法制备的茂金属催化剂和通过使用所述催化剂进行亚烷基聚合的方法。 制备负载在用于烯烃聚合的聚合物珠子上的高活性金属茂催化剂的方法,该方法包括以下步骤:将二乙烯基苯,乙烯基苄基氯和引发剂溶解在有机溶剂中,将其与水相的悬浮稳定剂混合, 在40〜80℃的温度下进行聚合,得到聚苯乙烯; 在环境温度下溶解在有机溶剂中的二元醇胺中使聚苯乙烯溶胀1至3天,得到具有二醇胺官能团的聚合物; 并使聚合物与溶解在有机溶剂中的茂金属化合物(CpM * Cl3)反应。 本发明的茂金属催化剂可以广泛用于乙烯聚合,苯乙烯聚合和共聚,同时代替常规的均相催化剂。
