Title
(EN) CROSSLINKABLE POLY(OXYALKYLENE)-CONTAINING POLYAMIDE PREPOLYMERS
(FR) POLYAMIDE PREPOLYMERES CONTENANT UN POLY(OXYALKYLENE) POUVANT ETRE RETICULE
Abstract
(EN) The present invention provides a water-soluble crosslinkable poly(oxyalkylene)­containing prepolymer. The crosslinkable poly(oxyalkylene)-containing copolymer prepolymer of the invention is prepared by reacting an amine-capped poly(oxyalkylene)­containing polyamide with a multifunctional compound having at least one one ethylenically unsaturated group and a function group coreactive with the capping amine groups of the amine-capped poly(oxyalkylene)-containing polyamide. The amine-capped poly(oxyalkylene)-containing polyamide is a copolymerization production of a mixture comprising: (a) at least one poly(oxyalkylene)diamine, (b) optionally at least one organic di­or poly-amine, (c) at least one dicarboxyl derivative, (d) optionally at least one polycarboxyl derivative, and (e) a carbodiimide. The crosslinkable poly(oxyalkylene)-containing prepolymer of the invention can find use in economically producing contact lenses which have improved thermal stability. In addition, the present invention provides method for making a medical device, preferably an ophthalmic device, more preferably a contact lens.
(FR) L'invention concerne un prépolymère contenant un poly(oxyalkylène) pouvant être réticulé hydrosoluble. Le prépolymère copolymérique contenant un poly(oxyalkylène) pouvant être réticulé de cette invention est préparé par mise en réaction d'un polyamide contenant un poly(oxyalkylène) à coiffe amine avec un composé multifonctionnel possédant au moins un groupe insaturé éthylénique et un groupe de fonction coréactif avec les groupes amine de coiffage du polyamide contenant un poly(oxyalkylène) à coiffe amine. Ce polyamide contenant un poly(oxyalkylène) à coiffe amine est un produit de copolymérisation d'un mélange comprenant: (a) au moins un poly(oxyalkylène)diamine, (b) éventuellement au moins un di- ou poly-amine organique, (c) au moins un dérivé dicarboxyle, (d) éventuellement au moins un dérivé polycarboxyle et (e) un carbodiimide. Le prépolymère contenant un poly(oxyalkylène) pouvant être réticulé de cette invention peut être utilisée pour la production à bon marché de lentilles de contact possédant une stabilité thermique améliorée. En outre, l'invention concerne un procédé de fabrication d'un dispositif médical, de préférence un dispositif ophtalmique, de préférence encore une lentille de contact.
