Description/Abstract This patent describes a process of producing linear alternating polymers of carbon monoxide and at least one olefinically unsaturated hydrocarbon under polymerization conditions in the presence of a palladium compound catalyst, an anion of a non-hydrohalogenic acid having a pKa less than about 6 and a bidentate ligand selected from bidentate phosphorus ligand or bidentate nitrogen ligand.^The improvement consists of employing as source of the anion, the quaternary phosphonium compound of the formula Z/sub 4/PA, wherein A is the anion of an oxygen containing acid having a pKa less than about 6 Z independently is hydrocarbyl group of from 1 to 20 carbon atoms inclusive.
