Title:
TRANSITION METAL COMPLEX, PROCESS FOR THE PREPARATION THEREOF, POLYMERIZATION CATALYST FOR OLEFINS CONTAINING THE COMPLEX, AND PROCESS FOR PRODUCING OLEFIN POLYMERS
Document Type and Number:
WIPO Patent Application WO/1997/003992
Kind Code:
A1
Abstract:
A transition metal complex represented by general formula (1) (wherein M1 is a Group 4 transition metal of the periodic table; A is a Group 16 element of the periodic table; B is a Group 14 element of the periodic table; Cp1 is a group having a cyclopentadiene-type anionic skeleton; X1, X2, R1, R2, R3, R4, R5 and R6 are each independently hydrogen, halogeno, optionally halogenated C1-C20 alkyl, optionally halogenated C1-C20 substituted silyl or the like, or alternatively R1, R2, R3, R4, R5 and R6 may be united arbitrarily to form a ring); a process for the preparation thereof; an intermediate of the transition metal complex; a process for the preparation of the intermediate; a polymerization catalyst for olefins containing the transition metal complex; and a process for producing olefin polymers.
