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.
