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 solid 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.
