Abstract
An improved process for the production of linear alternating polymers of carbon monoxide and at least one ethylenically unsaturated hydrocarbon comprises contacting the carbon monoxide and hydrocarbon under polymerization conditions in the presence of a reaction diluent and a novel catalyst composition formed from a compound of palladium, the anion of a strong non-hydrohalogenic acid and a bis(diethylphosphino)alkane.
Claims3
In the process of producing linear alternating polymers of carbon monoxide and at least one ethylenically unsaturated hydrocarbon by contacting the carbon monoxide and hydrocarbon under polymerization conditions in the presence of a liquid reaction diluent and a catalytic quantity of a catalyst composition formed from a compound of palladium, the anion of a strong, non-hydrohalogenic acid with a pKa below about 4 and a bidentate ligand of phosphorus, the improvement wherein the bidentate ligand is a bis(diethylphosphino)alkane.
