Geuze, M M

This patent describes an improvement in the process of producing a linear alternating polymer of carbon monoxide and at least one ethylenically unsaturated hydrocarbon by contacting under polymerization conditions a reaction mixture of the carbon monoxide and hydrocarbon in the presence of a catalyst composition formed from a palladium compound, the anion of non- hydrohalogenic acid having a pKa below about 6 and a bidentate ligand of phosphorus and a polymerization diluent. The improvement comprises providing to the reaction mixture from about 25% to about 85% of the catalyst composition at the outset of polymerization and subsequently providing the remainder of the catalyst composition when the concentration of polymer product has reached a value of at least 0.2 g per 100 g of the suspension of the polymer in the diluent.
