Abstract:
1. An article made from a maleated graft polymer comprising: a) a polymer component, said polymer component comprising a random copolymer produced by copolymerizing propylene and a comonomer selected from ethylene or other alpha-olefin having 4 to 6 carbon atoms, said copolymer having a crystallinity of from 0.1 weight % to 50 weight % from isotactic polypropylene sequences, a propylene content of from 68 to 92 mole percent, a comonomer content of from 8 to 32 mole percent and a melting point of said polymer component of from 25° C. to 105° C., wherein the copolymer has a heat of fusion of less than 45 J/g; and b) maleic anhydride.
