High temperature polymerization process using ionic catalysts to produce polyolefins

摘要

This invention relates to a process for polymerizing olefins at high pressures in a polymerization medium at high temperature utilizing an ionic olefin polymerization catalyst derived from the reaction of a cyclopentadienyl-containing transition metal compound having a hydrolyzable alkyl or hydride ligand with an ion exchange activator. The ionic catalyst system has been found to be highly active at temperatures of 160 DEG C. or greater, to provide a process capable of producing polymer products of desired chemical and physical properties at high production rates.
