Abstract
A method for modifying a heterophasic polymer composition comprises the steps of providing a compatibilizing agent, providing a heterophasic polymer composition comprising a propylene polymer phase and an ethylene polymer phase, mixing the compatibilizing agent and the heterophasic polymer composition, and generating free radicals in the propylene phase and the ethylene phase. At least a portion of the compatibilizing agent then reacts with free radicals in both the propylene polymer phase and the ethylene polymer phase to form a bond with a propylene polymer in the propylene polymer phase and a bond with an ethylene polymer in the ethylene polymer phase.
