ABSTRACT:
Improved compositions comprise polymer blends of a linear alternating polymer of carbon monoxide and at least one ethylenically unsaturated hydrocarbon with an ethylene/propylene
on-conjugated diene terpolymer, and, optionally, an acidic polymer containing moieties of an .alpha.-olefin and an .alpha.,.beta.-ethylenically unsaturated carboxylic acid. The blends demonstrate improved barrier properties.
