A process for the preparation of a copolymer of carbon monoxide with an olefinically unsaturated compound in which a powder of a copolymer of carbon monoxide with an olefinically unsaturated compound is suspended in a liquid diluent. The suspension is contacted with a catalyst composition which is soluble in the diluent and which is based on a Group VIII metal and a bidentate ligand. The catalyst composition is used in such a quantity that in the polymerization mixture more than 0.1 mmoles of the Group VIII metal is present per liter of liquid phase.

Process for the preparation of copolymers

A process for the preparation of a linear alternating copolymer of carbon monoxide with ethene and another olefinically unsaturated compound (A) wherein a copolymer of which the molar ratio (r.sub.1) of the monomer units originating in the olefinically unsaturated compound A to the monomer units originating in ethene is in the range of from 1:100 to 1:3, is prepared by contacting the monomers in the presence of a liquid diluent with a catalyst composition which is based on
