Patent ID: 7071259

Claim:
A composite comprising: (i) 30 to 98.995 weight percent polypropylene base resin; (ii) 1 to 70 weight percent dispersed component which is a polymer incompatible with said polypropylene base resin selected from the group consisting of ethylene-vinyl alcohol copolymer, polyamide, polyester, polyvinylchloride, polyvinylidenedichloride, ethylene-carbon monoxide copolymer and terpolymer, polycarbonate, polyether, high impact polystyrene, styrene-acrylonitrile copolymer and acrylonitrile-butadiene-styrene terpolymer; and (iii) 0.005 to 10 weight percent functionalized propylene polymer composition comprising (a) 5 to 95 weight percent, based on the weight of the functionalized composition, propylene-ethylene impact copolymer grafted with maleic anhydride and having a graft to melt flow rate ratio of 0.5 or above, said impact copolymer being a reactor-made intimate mixture of propylene homopolymer and ethylene-propylene copolymer rubber produced in a gas-phase, stirred-bed, multi-stage polymerization process, and (b) 95 to 5 weight percent, based on the weight of the functionalized composition, propylene homopolymer grafted with maleic anhydride.
