The process of producing a linear alternating polymer having units of CO and at least one olefinically unsaturated hydrocarbon compound by reacting carbon monoxide and olefinically unsaturated hydrocarbon compound in the gas phase in the substantial absence of liquid non-polymerizable diluent with a catalyst obtained by contacting (1) a compound of Group VIII metal selected from palladium, cobalt and nickel, (2) the anion of an oxygen-containing acid having a pKa less than 6, and (3) a bidette ligand of the formula wherein each M is phosphorus arsenic or antimony, R is a bivalent organic bridging group of 2 to 3 carbon atoms in the bridge and R/sup 1/, R/sup 2/, R/sup 3/ and R/sup 4/ independently are hydrocarbon or substituted hydrocarbon wherein the substituents are polar, under polymerization conditions in the gas phase.
