Novel approach to synthesizing poly(propylene)-graft-poly(styrene) (PP-g-PS).

Examines the design of a novel synthetic route used for preparing propylene-styrene copolymer. Catalysis of a propylene copolymerized with a 4-(3-butenyl) styrene by a propylene active catalyst to form a polymer which has a polypropylene main chain and some styryl side groups.
