A copolymerization process for copolymerising carbon monoxide and an olefin employs a catalyst comprising a Group VIII metal, for example palladium, and a bidentate ligand having general formula R R M -R-M R R where R represents a bridging group, M and R represent nitrogen, arsenic, antimony or, preferably phosphorus, and R , R , R and R preferably represent phenyl groups each having an alkoxy substituent and a sulphonyl substituent -SO2-OH or a salt or ester derivative. Such catalysts afford good reaction rates and good recycling properties. L'invention concerne un procédé de copolymérisation du monoxyde carbone et une oléfine, qui utilise un catalyseur constitué d'un métal du Groupe VIII, tel que le palladium, et d'un ligand bidenté de formule R R M -R-M R R . R représente un groupe de pontage; M et R de l'azote, de l'arsenic, de l'antimoine ou, de préférence, du phosphore; et R , R , R et R , de préférence, des groupes de phényle, chacun ayant un substituant alcoxy et un substituant sulfonyle -SO2-OH ou un sel ou dérivé ester. De tels catalyseurs offrent de bonnes vitesses de réaction et de bonnes propriétés de recyclage.
