Abstract

La invencion se refiere a un proceso para la produccion de moldeos, en particular lentes de contacto, en donde se reticula un polímero reticulable soluble en agua en solucion, y a moldeos, en particular lentes de contacto, que se pueden obtener mediante este proceso. La presente invencion de la misma manera se refiere a polímeros reticulables novedosos que comprenden unidades que contienen un grupo reticulable, unidades que contiene un grupo ácido, y/o unidades que contienen un grupo básico, que se pueden emplear en el proceso novedoso, en particular derivados de un alcohol polivinílico que tiene un peso molecular de cuando menos aproximadamente 2,000, y a polímeros reticulados, bien sea homopolímeros o copolímeros, hechos a partir de estos polímeros reticulables novedosos, a un proceso para la preparacion de los polímeros reticulables novedosos, y a los homopolímeros y copolímeros que se pueden obtener a partir del mismo, a moldeos hechos a partir de estos homopolímeros o copolímeros, en particular lentes de contacto hechos a partir de estos homopolímeros o copolímeros, y a un proceso para la produccion de lentes de contacto utilizando estos copolímeros o copolímeros.
