Polymers having non-thrombogenic properties can be prepared by copolymerising monomers of at least three classes selected from (a) monomers having sulphate groups, (b) monomers having sulphonate groups, (c) monomers having sulphamate groups, and (d) monomers having polyoxyalkylene ether groups, (e) monomers having zwitterionic groups. The monomers can additionally be provided with anti-thrombogenic properties by including an additional comonomer having a pendant heparin (or hirudin, warfarin or hyaluronic acid) group. The polymers can be used as coating materials for medical devices, such as tubing or connectors, in order to provide them with non-thrombogenic, and optionally anti-thrombogenic, properties.

L'invention porte sur des polymères dotés de propriétés non thrombogènes pouvant se préparer par copolymérisation de monomères d'au moins trois classes sélectionnés parmi: (a) des momomères présentant des groupes sulfate, (b) des momomères présentant des groupes sulfonate, (c) des momomères présentant des groupes sulfamate, (d) des momomères présentant des groupes éther polyoxyalkylénique, (e) des momomères présentant des groupes zwittérioniques. Lesdits monomères peuvent en outre présenter des propriétés anti-thrombogènes lorsqu'on leur ajoute un comonomère additionnel à groupe disponibles héparine (ou hirudine, ou warfarine ou acide hyaluronique). Lesdits polymères peuvent servir de matériau de revêtement pour dispositifs médicaux, tels que tubes ou raccords, pour leur conférer des propriétés non thrombogènes et éventuellement anti-thrombogènes.
