The present invention provides an olefin polymerization catalyst component comprising a transition metal compound represented by general formula (1)
LmCpnMX1X2 (1)
[wherein M is a transition metal atom of Group 4 in a periodic table, Cp represents a cyclopentadienyl group, a substituted cyclopentadienyl group, an indenyl group, a substituted indenyl group, a fluorenyl group, or a substituted fluorenyl group, and other symbols have the meanings as described in the specification], an olefin polymerization catalyst containing the catalyst component as a transition metal component, and a method of producing a polyolefin using the catalyst.
According to the present invention, polyolefins having a wide molecular weight distribution and excellent moldability and containing small amounts of low molecular weight components can be produced with high activity.
本发明提供了一种烯烃聚合催化剂组分,它由通式(1)表示的过渡金属化合物组成
LmCpnMX1X2 (1)
[其中M是元素周期表中第4族的过渡金属原子,Cp代表环戊二烯基、取代环戊二烯基、茚基、取代茚基、芴基或取代芴基,其他符号的含义如说明书所述],一种含有该催化剂组分作为过渡金属组分的烯烃聚合催化剂,以及一种使用该催化剂生产聚烯烃的方法。
根据本发明,可生产出具有宽分子量分布和优异成型性且含有少量低分子量组分的高活性聚烯烃。
