Abstract
A graft copolymer having a polyolefinic main chain with muconic acid groups pendant therefrom. The acid groups are bonded to the backbone of the polyolefin by free radical addition across a muconic acid double bond. Preferably, the copolymer is prepared via a reactive extrusion process. The copolymer's applications include use as a reactive compatibilizer for polymer blends. The preferred polyolefin is polypropylene.
