ABSTRACT:
Linear alternating copolymers of carbon monoxide and an unsaturated bicyclic carboxylic acid compound are produced in the presence of a catalyst composition formed from a palladium compound, an anion of certain strong acids and a bidentate ligand of nitrogen. When the bidentate ligand is a bidentate ligand of phosphorus and an ethylenically unsaturated hydrocarbon is also present, a mixture of polymers is produced which includes the linear alternating copolymer.
