Copolymerization of carbon monoxide and olefin with nitrogen containing phosphine ligand catalyst

摘要

Polymers of carbon monoxide and at least one ethylenically unsaturated hydrocarbon, e.g., ethylene, are produced in the presence of novel catalyst compositions formed from a palladium compound, an anion of a non- hydrohalogenic acid having a pKa less than about 2 and certain bidentate ligands containing atoms of phosphorus and nitrogen.
