Patent ID: 7030188

Claim:
A composition comprising (1) 30 to 98.5 weight percent highly crystalline polypropylene base resin having a tacticity index greater than 90 and melt flow rate from 0.5 to 100 g/10 min.; (2) 1 to 70 weight percent polymers which is incompatible with said 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 (3) 0.25 to 10 weight percent grafted propylene-ethylene impact copolymer having an ethylene content from 5 to 30 percent and molecular weight distribution of 7 or less and which is a reactor-made intimate mixture of propylene homopolymer and 20 weight percent or more propylene-ethylene copolymer grafted with 1 weight percent or more maleic anhydride.
