A catalyst for polymerization of an olefin is provided which comprises a metallocene compound having a specified substituted fluorenyl group, and a compound capable of reacting the metallocene compound to form a cationic metallocene compound. With this compound, a high-molecular olefin polymer having narrow composition distribution and narrow molecular-weight distribution can be obtained at a polymerization temperature of not lower than 120°C.
本发明提供了一种烯烃聚合催化剂,它包括一种具有特定取代芴基的茂金属化合物和一种能与茂金属化合物反应生成阳离子茂金属化合物的化合物。使用这种化合物,可以在不低于 120°C 的聚合温度下获得成分分布窄、分子量分布窄的高分子烯烃聚合物。
