T 1510 A B S T R A C T PROCESS FOR THE PREPARATION OF POLYMERS OF CARBON MONOXIDE WITH ONE OR MORE OLEFINICALLY UNSATURATED COMPOUNDS Process for the preparation of polymers, in which 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 are prepared by contacting the monomers at elevated temperature and pressure and substantially in the absence of a liquid non-polymerizable diluent with a catalyst based on a) a Group VIII metal compound, b) an anion of an acid with a pKa of at least 2, in a quantity of at least 5 mol per mol of the Group VIII metal, and 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.
