Title:
CATALYST FOR OLEFIN POLYMERIZATION AND PROCESS FOR PREPARING OLEFIN POLYMER BY USING THE SAME
Document Type and Number:
WIPO Patent Application WO/1987/002370
Kind Code:
A1
Abstract:
A novel catalyst which catalyzes homopolymerization of an olefin having 2 or more carbon atoms or copolymerization of two or more olefins, and a process for preparing olefin polymers by using it. High-molecular olefin polymers can be produced in high yields by polymerizing or copolymerizing an olefin by using a catalyst system composed of a transition metal compound of M(R)$(1,3)$(OR')mXn-($(1,3)$+m) and aluminooxane or a catalyst system composed of a transition metal compound of M(R)$(1,3)$(OR')mXn-($(1,3)$+m), aluminooxane, and an organic compound having at least two hydroxy groups.
