Abstract
Polymer blends comprising a major proportion of a polyamide polymer and lesser proportions of a linear alternating polymer of carbon monoxide and at least one ethylenically unsaturated hydrocarbon and of an acidic polymer containing moieties of .alpha.,.beta.-ethylenically unsaturated carboxylic acid demonstrate improved properties of melt strength and melt elasticity and, over a narrower range of concentration of the linear alternating polymer, improved mechanical properties.
