ABSTRACT:
An improved process for the production of linear alternating polymers of carbon monoxide, functionally-substituted ethylenically unsaturated compound wherein at least one carbon atom separates the functional substitution and the ethylenic unsaturation and, optionally, an ethylenically unsubstituted hydrocarbon, which comprises contacting the carbon monoxide and unsaturated compound under polymerization conditions in the presence of a reaction diluent and a catalyst composition formed from a compound of palladium, the anion of a strong non-hydrohalogenic acid and a tetraalkyl diphosphine liqand.
