ABSTRACT:
Blends comprising a major proportion of linear alternating polymer of carbon monoxide and at least one ethylenically unsaturated hydrocarbon, with lesser proportions of a polymeric polyamide, a carboxylated partially hydrogenated block copolymer and, optionally, an acidic polymer containing moieties of an .alpha.-olefin and an .alpha.,.beta.-ethylenically unsaturated hydrocarbon wherein, optionally, a portion of the carboxyl groups are neutralized with non-alkali metal, demonstrate a balance of strength and improved low temperature toughness.
