ABSTRACT:
In the process for the production of a linear alternating polymer of carbon monoxide and at least one ethylenically unsaturated hydrocarbon, the liquid portion of the product mixture is suitable for recycle as the catalyst composition mixture in subsequent polymerizations when the linear alternating polymer produced has a limiting viscosity number, measured in m-cresol at 60.degree. C., of from about 0.5 dl/g to about 2.5 dl/g and a melting point of at least 225.degree. C.
