Process for the preparation of linear polymers of carbon monoxide with one or more olefinically unsaturated compounds in which polymers the units originating from carbon monoxide and the units originating from the olefinically unsaturated compounds are present in a substantially alternating order by contacting the monomers in a continuous manner at elevated temperature and pressure with a catalyst based on a) a Group VIII metal compound, b) a halomonocarboxylic acid, c) a dentate ligand containing at least two phosphorus-, nitrogen- or sulphur-containing dentate groups which dentate ligand can form a complex with the Group VIII metal, and which catalyst contains less than 6 mol of component b) per mol Group VIII metal.
