ABSTRACT:
Novel linear alternating copolymers of carbon monoxide and a 1,2-alkadiene are produced by contacting the carbon monoxide and alkadiene under polymerization conditions in the presence of a catalyst composition formed from a palladium compound, the anion of a non-hydrohalogenic acid having a pKa less than 4 and a bidentate ligand of nitrogen. The novel copolymers are formed in a mixture with linear alternating copolymer of carbon monoxide and ethylenically unsaturated hydrocarbon when an ethylenically unsaturated hydrocarbon is additionally present in the polymerization mixture.
