Abstract
Compositions which have substantial weatherability and impact resistance include a substantially uniform blend of an acrylonitrile/styrene/acrylic polymeric material and a component selected from (A) polymeric materials including units derived from ethylene, carbon monoxide and copolymerizable ethylenically unsaturated organic compounds, (B) graft polymer components including ethylene-propylene-non-conjugated diene terpolymers grafted with styrene and acrylonitrile monomers, and mixtures thereof. Methods for making such compositions include forming a substantially uniform physical mixture of such polymeric material and component.
