ABSTRACT:
An improved process for the production of linear alternating polymers of carbon monoxide and at least one ethylenically unsaturated hydrocarbon employs a novel catalyst composition formed from a compound of palladium, an anion of a strong non-hydrohalogenic acid and a supported bidentate ligand of phosphorus. The improved process is characterized by a reduced level of reactor fouling. The polymer products are useful as engineering thermoplastics.
