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

Process for the preparation of a linear alternating copolymer of carbon

A process for the copolymerization of carbon monoxide with an olefinically unsaturated compound in which a solid particulate material is suspended in a liquid diluent in which the polymer to be produced forms a suspension. The monomers are contracted in the liquid diluent containing the suspended solid particulate material with a catalyst composition which is based on a source of a Group VIII metal and a boron hydrocarbyl compound.

Process for the copolymerization of carbon monoxide with an olefinically

A process for the copolymerization of carbon monoxide with an olefinically unsaturated compound in which the monomers are contacted in the presence of a liquid diluent and a protic compound with a catalyst composition which is based on a source of a Group VIII metal and a hydrocarbylborane. A stirring power is transmitted to the polymerization mixture of at least 0.25 kW/m.sup.3.
