Abstract

Cette invention se rapporte à des membranes biocompatibles destinées à des biocapteurs. Lesdites membranes sont composées de polymères qui peuvent être préparés à partir (a) d'un diisocyanate, (b) d'un polymère hydrophile, (c) d'un polymère de siloxane possédant des groupes fonctionnels au niveau de ses terminaisons de chaînes, et éventuellement (c) d'un allongeur de chaîne.
