Title (EN) REVERSIBLE CROSSLINKED POLYMERS
(FR) POLYMÈRES À RÉTICULATION RÉVERSIBLE
Abstract:
(EN) The present invention provides reversibly crosslinked polymers and methods for producing and using the same. In particular, reversibly crosslinked polymers of the invention comprise polyesters comprising thiol groups as crosslinking moieties. Oxidation of thiol groups affords crosslinked polymer comprising a disulfide linkage and reduction of the disulfide linkage provides non-crosslinked polymer. In some embodiments, polymers of the invention are degradable and are biocompatible.
(FR) La présente invention concerne des polymères à réticulation réversible et des procédés permettant de les produire et de les utiliser. En particulier, les polymères à réticulation réversible de l'invention comprennent des polyesters comprenant des groupes thiols comme fractions de réticulation. L'oxydation des groupes thiols donne un polymère réticulé comprenant une liaison disulfure et la réduction de la liaison disulfure donne un polymère non réticulé. Dans certains modes de réalisation, les polymères de l'invention sont dégradables et sont biocompatibles.
