Abstract
A process for the production of linear alternating polymers of carbon monoxide and at least one ethylenically unsaturated hydrocarbon employs a novel catalyst composition form from a palladium compound, the anion of certain string acids and a bidentate ligand of sulfur. The copolymer of carbon monoxide and a styrene monomer by such process is regioregular but not stereoregular.
