ABSTRACT:
Improved compositions comprise polymer blends of a linear alternating polymer of carbon monoxide and at least one ethylenically unsaturated hydrocarbon with a high rubber graft copolymer, and, optionally, an acidic polymer containing moieties of an .alpha.-olefin and an .alpha.,.beta.-ethylenically unsaturated carboxylic acid. The blends demonstrate improved toughness and impact strength at both ambient and low temperatures.
