ABSTRACT:
Improved compositions comprise isomorphic polymer blends of at least two linear alternating polymers of carbon monoxide and one or more ethylenically unsaturated hydrocarbons. A preferred composition is the combination of a linear alternating polyketone copolymer of carbon monoxide and ethylene with a linear alternating polyketone terpolymer of carbon monoxide, ethylene, and a second ethylenically unsaturated hydrocarbon of at least 3 carbon atoms, particularly propylene.
