Catalytic copolymerization of co/olefin with ketone additive
The process of producing a linear alternating polymer of carbon dioxide and at least one ethylenically unsaturated hydrocarbon of 2 to 20 carbon atoms inclusive is described. It consists of contacting carbon monoxide and the hydrocarbon under polymerization conditions in the presence of a catalyst composition prepared from a palladium compound, a non-transition metal salt of a non-hydrohalogenic acid having a pKa less than about 6, a bidentate phosphorus ligand of the formula R/sup 1/R/sup 2/--P--R--P--R/sup 3/R/sup 4/ in which R/sup 1/,R/sup 2/,R/sup 3/ and R/sup 4/ independently are organic radicals of from 1 to 14 carbon atoms inclusive and R is a divalent bridging group of up to 20 carbon atoms and up to 3 carbon atoms in the bridge, and a ketone of from 3 to 20 carbon atoms inclusive and recovering from the resulting product mixture the linear alternating polymer of carbon monoxide and the hydrocarbon.
