Abstract
An improved process for the production of linear alternating polymers of carbon monoxide and hydrocarbon norbornene-type compounds comprises contacting the monomers in the presence of a catalytic quantity of a catalyst composition formed from a palladium compound, the anion of a strong non-hydrohalogenic acid and a bidentate ligand of phosphorus under polymerization conditions including a polymerization temperature above 100.degree. C. In an alternate modification, lower .alpha.-olefin is included in the reaction mixture and additional polymeric products are obtained.
