| description | Novel catalyst compositions for copolymerizing ethene and carbon monoxide, characterized in that they comprise: a) a compound of a Group VIII metal chosen from palladium, cobalt and nickel, b) an anion of an acid with a pKa of less than 6, and c) a bidentate ligand of the general formula R R -M-R-M-R R , wherein M represents phosphorus, arsenic or antimony, R is a bivalent organic bridging group containing two or three carbon atoms in the bridge and R , R , R and R represent hydrocarbon groups which may or may not be substituted with polar groups, on the understanding that at least one hydrogen atom in at least one of the groups R , R , R and R is substituted with a polar substituent. y |
