Process for the copolymerization of carbon monoxide with an olefinically unsaturated compound

摘要

A process for the copolymerization of carbon monoxide with an olefinically unsaturated compound comprising contacting the monomers 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, with application of a stirring power transmitted to the polymerization mixture of at least 0.25 kW/m<3>.
