Abstract
Improved polymer blends comprise (a) a linear alternating polymer of carbon monoxide and at least one ethylenically unsaturated hydrocarbon, (b) a polymeric polyamide, (c) a maleated, partially hydrogenated elastomeric block copolymer, and optionally (d) an acidic polymer of an .alpha.-olefin and an .alpha.,.beta.-ethylenically unsaturated carboxylic acid wherein, optionally, a portion of the carboxylic acid groups have been neutralized with non-alkali metal. The blends demonstrate a good balance of strength and toughness.
Claims11
A ternary polymer blend having improved mechanical properties comprising:
- (1) a major amount of a linear alternating polymer of carbon monoxide and at least one ethylenically unsaturated hydrocarbon;
- and lesser amounts of (2) a polymeric polyamide having recurring amide moieties in the polymer chain;
- (3) and a maleated, partially hydrogenated elastomeric copolymer in which (1) functions as a matrix and (2) functions as a compatibilizer.
A ternary polymer blend having improved mechanical properties comprising:
- (1) about 5 to about 85 percent by weight of a linear alternating polymer of carbon monoxide and at least one ethylenically unsaturated hydrocarbon;
- (2) about 2 to about 20 percent by weight of a polymeric polyamide having recurring amide moieties in the polymer chain;
- (3) about 0.5 to about 20 percent by weight of a maleated, partially hydrogenated elastomeric copolymer in which (1) functions as a matrix and (2) functions as a compatibilizer.
A ternary polymer blend having improved mechanical properties comprising:
- (1) substantially equal amounts of a linear alternating polymer of carbon monoxide and at least one ethylenically unsaturated hydrocarbon and of a polymeric polyamide having recurring amide moieties in the polymer chain, and (2) a lesser amount of a maleated partially hydrogenated elastomeric copolymer in which (1) functions as a matrix and (2) functions as a compatibilizer.
