ABSTRACT:
In the process of producing a linear alternating polymer of carbon monoxide and at least one ethylenically unsaturated hydrocarbon in a diluent in the presence of a palladium salt, the anion of a strong non-hydrohalogenic acid, and a phosphine ligand, improved polymer bulk density and polymerization rates are obtained when employing as the diluent a ketone/alcohol mixture having at least 50% by volume of an aliphatic ketone which has at most 10 carbon atoms and at least 5% by volume of an aliphatic alcohol which has at most 10 carbon atoms.
