Title:
PRODUCTION OF OLEFIN POLYMER
Document Type and Number:
Japanese Patent JP3217416
Kind Code:
B2
Abstract:
PURPOSE: To produce an α-olefin homopolymer or a copolymer of at least two kinds of α-olefins at a high efficiency without the necessity for a large amt. of organoaluminum compd.
CONSTITUTION: An α-olefin is homopolymerized or copolymerized with another a-olefin in the presence of a catalyst system mainly comprising a transition metal compd. (A), a compd. (B) which reacts with the transition metal compd. to form an ionic complex, and an organoaluminum compd. (C), or a catalyst system mainly comprising a transition metal compd. (A1) of the formula: M1 R1aR2bR3cR4d [wherein is a transition metal; R1, R2, R3, and R4 are each a ligand with σ bonds, a ligand with chelate bonds, or a Lewis base provided that they may be the same or different ; and a, b, c, and d are each 0-4], compd. B, and compd. C, or a catalyst system mainly comprising compd. Al and compd. B.
