OLEFIN POLYMERIZATION PROCESS IN THE PRESENCE OF A RADICAL GENERATING SYSTEM

摘要

An olefin polymerization process comprises gas-phase polymerization of at least one olefin monomer in a reactor using a Ziegler-Natta or metallocene catalyst system in the presence of at least one suitable radical-generating compound in an amount sufficient for polymer modification and subsequent stabilization of such compound and generated radicals before post-reactor heat processing.
