Abstract
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.
Claims12
A process for the copolymerization of carbon monoxide with an olefinically unsaturated compound comprising:
- (a) contacting the monomers in the presence of a liquid diluent and a lower alcohol with a catalyst composition which comprises a source of a Group VIII metal, and a hydrocarbylborane, and (b) transmitting a stirring power to the polymerization mixture of at least 0.25 kW/m.sup.3, wherein the rate of decay of polymerization is no more than 13% over the course of an hour.
