Disclosed is a process for making a surface of a substrate biocompatible, which comprises subjecting at least one monomer of the general formula: R-(A)a, (in which R is a mono- or diolefinically unsaturated organic radical, having the valency a, A is a carboxyl group -COOH, a sulfuric acid group -OSO2OH, a sulfonic acid group -SO3H, a phosphoric acid group -OPO(OH)2, a phosphonic acid group -PO(OH)2, a phosphorous acid group -OP(OH)2, a phenolic hydroxyl group or a salt or an ester thereof and a is an integer from 1 to 6) to graft-polymerization under radiative induction onto an activated surface of the substrate, with the proviso that when A is a carboxyl group -COOH or a salt or an ester thereof, either the monomer contains at least one further different radical A is used together with at least one further monomer in which A is other than a carboxyl group or a salt or ester thereof. The process is suitable for producing medical or biotechnical articles, storage containers or packaging.

On divulgue un procédé pour rendre biocompatible la surface d'un substrat, qui consiste à soumettre au moins un monomère de formule générale : R-(A)a, (où R est un radical organique mono- ou dioléfiniquement insaturé, de valence a, A est un groupe carboxyle -COOH, un groupe acide sulfurique -OSO2OH, un groupe acide sulfonique -SO3H, un groupe acide phosphorique -OPO(OH)2, un groupe acide phosphonique -PO(OH)2, un groupe acide phosphoreux -OP(OH)2, un groupe hydroxyle phénolique ou un sel ou un ester de ces derniers et a est un nombre entier compris entre 1 et 6) pour polymérisation avec greffe sous induction radiative sur une surface activée du substrat, à la condition que lorsque A est un groupe carboxyle -COOH ou un sel ou un ester de ce dernier, soit que le monomère contient au moins un autre radical A qui est différent, soit qu'on l'utilise avec au moins un autre monomère où A est un groupe autre qu'un groupe carboxyle ou un sel ou ester de ce dernier. Le procédé convient pour la fabrication d'objets médicaux ou biotechniques, de contenants d'emballage ou d'entreposage.
