Process for the copolymerization of carbon monoxide with an olefinically unsaturated compound |
abstract |
A process for the copolymerization of carbon monoxide with an olefinically unsaturated compound comprising contacting the monomers with a catalyst composition which is based on a source of a Group VIII metal and a boron hydrocarbyl compound and adding additional boron hydrocarbyl compound to the polymerization mixture during the copolymerization or when the catalyst has lost its activity; and a process for recycling a polymerization catalyst comprising the steps of recovering a Group VIII metal composition from a preceding copolymerization process for the preparation of a copolymer of carbon monoxide and an olefinically unsaturated compound and adding a boron hydrocarbyl compound to the Group VIII metal composition. |
