Catalysts for the polymerization of poly (ethylene glycol) and catalysts for their preparation (CATALYST AND PROCESS FOR A ZIEGLER POLYMERISATI0N)

摘要

More particularly, the present invention relates to a catalyst suitable for preparing an olefin polymer composed of an organometallic compound and a transition metal-imidoaryl complex via giegler polymerization, Characterized in that the metal-imidoaryl complex contains at least one amido group bonded to the transition metal and the aryl group in the complex is an o, o-disubstituted phenyl group.
