Abstract

Un elastómero termoplástico útil como material para lente de contacto que es el producto de polimerización de una mezcla de monómeros que incluye: (A) un prepolímero terminado en hidroxi- o amino preparado por reacción de los siguientes componentes: (a) al menos un 60 % en moles de un monómero con contenido en silicona etilénicamente insaturado, (b) de 2, 5 a 20 % en moles de un monómero etilénicamente insaturado que contiene un radical hidroxilo o amino, (c) de 2, 5 a 20 % en moles de un agente de transferencia de cadena seleccionado entre hidroximercaptanos y amino mercaptanos que proporciona al prepolímero radicales con función hidroxilo o amino, y (d) de 0 a 20 % en moles de un monómero etilénicamente insaturado distinto a los monómeros (a), (b) ¿ o (c), basándose el porcentaje molar de los componentes (a), (b), (c) y (d) en la cantidad molar total de dichos componentes; y (B) al menos un monómero de diisocianato reactivo con radicales con función hidroxilo o amino del prepolímero.
