Abstract

See full text

Modified polymers, particularly polyolefins with improved flow over that of polyolefin alone, are produced by reacting polypropylene, maleic anhydride monomer, and a peroxy initiator in a twin-screw extruder. The maleic anhydride monomer is injected as a fluid and is grafted onto the base polypropylene during the degradation/chain scissioning process. Novel, highly-grafted polymers with high melt flow and other useful properties are produced in pellet form.
