Title:
【発明の名称】オレフィン重合用固体状触媒成分およびこの触媒成分を用いたオレフィンの重合方法
Document Type and Number:
Japanese Patent JP2940684
Kind Code:
B2
Abstract:
The present invention relates to solid catalyst components for olefin polymerization formed by prepolymerizing at least two types of alpha -olefin on an olefin polymerization catalyst comprising a solid titanium catalyst component, an organometallic compound catalyst component, and if necessary, an electron donor, to olefin polymerization catalyst comprising said soild catalyst component for olefin polymerization, an organometallic compound catalyst component, and if necessary, an electron donor, and to processes for olefin polymerization using said olefin polymerization catalyst. According to the present invention, there can be manufactured olefin polymer particles having low adhesive among the polymer particles as well as good particle distribution and excellent granular properties even when they contain a large amount of an amorphous olefin polymer portion.
