Title (EN) ANTITHROMBOGENIC POLYMERS
(FR) POLYMERES ANTITHROMBOGENES
Abstract:
(EN) Polymers bearing heparin residues in bioactive form may be used in blood-contacting devices and as affinity chromatography agents. The polymers are produced by (a) polymerising heparin-bearing vinyl, acrylate, acrylamide or acrylonitrile monomers, (b) free-radical polymerisation of monomers in the presence of heparin or (c) grafting heparin to polymers via amino-group containing side chains.
(FR) On peut utiliser des polymères comportant des résidus d'héparine sous forme bioactive dans des dispositifs entrant en contact avec le sang et comme agents d'affinité chromatographique. On produit ces polymères par: (a) polymérisation de monomères de vinyle, d'acrylate, d'acrylamide ou d'acrylonitrile comportant de l'héparine, (b) polymérisation radicale libre de monomères en présence d'héparine ou (c) greffe d'héparine sur des polymères par l'intermédiaire d'un groupe aminé contenant des chaines latérales.
