CA 2387442

A method of modifying a polymeric surface of a substrate including: (iii) providing the polymeric surface with functional groups; and (iv) contacting the surface with (a) a polyamine compound reactive with the surface functional groups said polyamine comprising at least four amine groups including at least two amine groups selected from primary and secondary amine groups and (b) a crosslinking agent reactive with the polyamine; to provide a crosslinked network grafted to the substrate surface.

Ce procédé de modification d'une surface polymère d'un substrat comprend les étapes suivantes consistant: (iii) à préparer la surface polymère au moyen de groupes fonctionnels, et (iv) à mettre cette surface en contact avec (a) un composé polyamine réagissant avec les groupes fonctionnels de la surface, cette polyamine comprenant au moins deux groupes amines choisis parmi des groupes d'amines primaires et secondaires, et (b) un agent de réticulation réagissant avec la polyamine, de façon que le réseau réticulé soit greffé sur la surface du substrat.
