ABSTRACT:
The invention is a process for working up a linear alternating copolymer of carbon monoxide, ethylene and optionally at least one olefinically unsaturated hydrocarbon, which process comprises contacting the copolymer with an organic solvent in the absence of molecular oxygen and under conditions effective to reduce the amount of impurities in the copolymer, and drying the copolymer in the absence of molecular oxygen.
