Abstract
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.

A process for the copolymerization of carbon monoxide with an olefinically unsaturated compound comprising (a) suspending a solid particulate material in a liquid diluent in which the polymer to be produced forms a suspension, and (b) contacting the monomers in the liquid diluent containing the suspended solid particulate material with a catalyst composition comprising a source of a Group VIII metal and a boron hydrocarbyl compound, wherein the solid particulate material comprises between 0.1 and 20% wt of diluent, a bulk density of between 50 and 1000 kg/m.sup.3, an average particle size of between 10.sup.-6 and 10.sup.-3 m and stabilizes said process.
