A catalyst system suitable for the copolymerization of carbon monoxide with an ethylenically unsaturated compound which catalyst system is based on (a) a source of palladium cations, and (b) a bidentate ligand of the general formula R1R2P-CH2-CH2-PR3R4 wherein R1 represents a phenyl group substituted with a polar group at one or both ortho-positions and/or the para-position with respect to the phosphorus atom to which the said phenyl group is linked, and R2, R3 and R4 independently represent a substituted or non-substituted hydrocarbyl group; and a process for the preparation of copolymers of carbon monoxide and an ethylenically unsaturated compound by reacting the monomers in the presence of said catalyst system.

Système de catalyseur conçu pour la copolymérisation de monoxyde de carbone avec un composé éthyléniquement insaturé, ce système étant basé sur: (a) une source de cations de palladium, et (b) un ligand bidenté de la formule générale R?1¿R?2¿P-CH¿2?-CH¿2?-PR?3¿R?4¿ dans laquelle R?1¿ représente un groupe phényle substitué par un groupe polaire au niveau d'une ou des deux positions ortho et/ou de la position para par rapport à l'atome phosphore auquel ce groupe phényle est lié, et R?2¿, R?3¿ et R?4¿ représentent indépendamment un groupe hydrocarbyle substitué ou non. L'invention concerne également un procédé de préparation de copolymères de monoxyde de carbone et d'un composé éthyléniquement insaturé qui consiste à faire réagir les monomères en présence dudit système de catalyseur.
