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 .degree.C or greater, to provide a process capable of producing polymer products of desired chemical and physical properties at high production rates.
