Title (EN) CHAIN-EXTENDED POLYSILOXANE CROSSLINKERS WITH DANGLING HYDROPHILIC POLYMER CHAINS
(FR) AGENTS DE RÉTICULATION DE POLYSILOXANE À CHAÎNE ÉTENDUE AVEC DES CHAÎNES DE POLYMÈRE HYDROPHILE PENDANTES
Abstract:
(EN) The invention provide a class of linear chain-extended polysiloxane crosslinkers which comprises two terminal ethylenically unsaturated groups, at least two polysiloxane segments, and dangling hydrophilic polymer chains each covalently attached to a divalent organic radical separating each pair of adjacent polysiloxane segments. The present invention is also related to a polymer comprising crosslinking units derived from chain-extended polysiloxane crosslinker of the invention and to ophthalmic lenses comprising such a polymer.
(FR) L'invention concerne une classe d'agents de réticulation de polysiloxane linéaire à chaîne étendue qui comprend deux groupements terminaux éthyléniquement insaturés, au moins deux segments de polysiloxane, et des chaînes de polymère hydrophile pendantes chacune attachée par covalence à un radical organique divalent séparant chaque paire de segments de polysiloxane adjacents. La présente invention concerne aussi un polymère comprenant des unités de réticulation dérivées de l'agent de réticulation de polysiloxane à chaîne étendue de l'invention et des lentilles ophtalmiques comprenant un tel polymère.
