ABSTRACT:
This invention relates to a polymer composition comprising (A) from about 55% to about 75% by weight of at least one polyolefin, (B) from about 2% to about 12% by weight of at least one reaction product of an alpha, beta unsaturated carboxylic reagent and a polyolefin, and (C) from 15% to about 35% by weight of filler. In one aspect, the polymer compositions also include (D) at least one copolymer of ethylene and an olefin, (E) at least one polyamide, or (F) a mixture of (D) and (E). These compositions provide articles and films with improved scratch resistance and hardness. These compositions have improved processing character because their low coefficient of friction.
