Abstract
An improved process for the production of linear alternating polymers of carbon monoxide and at least one ethylenically unsaturated hydrocarbon comprises the continuous process wherein the carbon monoxide and ethylenically unsaturated hydrocarbon are contacted under polymerization conditions in the presence of a catalyst composition formed from a compound of palladium, a non-hydrohalogenic acid and a bidentate ligand of phosphorus, the molar ratio of the acid to palladium being below 6.
