A process for preparing high molecular weight, linear interpolymers of carbon monoxide with at least one alpha-olefin having from two to eight carbon atoms which comprises reacting under substantially anhydrous conditions carbon monoxide with from about 1 to about 30 moles of alpha-olefin per mole of carbon monoxide at a temperature from about 75°C to about 150°C and a pressure of from about 10 to about 1,000 atmospheres in the presence of a solvent selected from the group consisting of hexafluoroisopropanol and meta-cresol and in the presence of from about 0.005 to about 50% by weight based on monomer charged of catalyst consisting essentially of a compound selected from the group consisting of anhydrous nickel (II) cyanide, complex nickel salts comprising a tetracyanonickelate (II) anion and a cation selected from the group consisting of R4N, R4P, R3Sand R4Aswherein R is an alkyl, aryl or cycloalkyl group of from about 3 to about 10 carbon atoms, and mixtures of said anhydrous nickel (II) cyanide and said complex nickel salt.
