Abstract

Cette addition apporte des changements et perfectionnements au corps façonné en polymere et à son procédé de production décrits au brevet principal. Ce corps est constitué par un polymère SIN constitué par des polymères hydrophile et hydrophobe réticulés, dans lesquels le polymère hydrophile est tel que défini au brevet principal, le polymère hydrophobe réticulé étant préparé à partir d'un ou plusieurs prépolymères de poly(organosiloxanes) pouvant subir une réticulation simultanément à la polymérisation et à la réticulation de la partie hydrophile et indépendamment de celle-ci. Ce polymère convient de façon particulière pour la production de lentilles de contact.
