POLYMERIZATION OF ALPHA-OLEFINS WITH TRANSITION METAL CATALYSTS BASED ON BIDENTATE LIGANDS CONTAINING PYRIDINE OR QUINOLINE MOIETY

摘要

Disclosed is a novel bidentate pyridine transition metal catalyst having general formula (1), where Y is 0, S, NR, (2), or (3), each R is independently selected from hydrogen or C1 to C6 alkyl, each R' is independently selected from C1 to C6 alkyl, C1 to C6 alkoxy, C6 to C16 aryl, halogen, or CF3, M is titanium, zirconium, or hafnium, each X is independently selected from halogen, C1 to C6 alkyl, C1 to C6 alkoxy, or (4), L is X, cyclopentadienyl, C1 to C6 alkyl substituted cyclopentadienyl, indenyl, fluorenyl, or (5), "m" is 0 to 4, and "n" is 1 to 4. Also disclosed is a method of making a poly-.alpha.-olefin comprising polymerizing an .alpha.-olefin monomer using that catalyst or a catalyst that has general formula (6), where Y, M, L, X, and R' were previously defin ed and each "p" is independently selected from 0 to 3.
