Abstract

PROCESO PARA EL TRATAMIENTO DE SUPERFICIES POLIMERICAS HIDROFOBAS, QUE FORMA PORCIONES HIDROXILAS Y QUE CONSISTE EN LA OZONIZACION DE LA SUPERFICIE DE DICHO POLIMERO HIDROFOBO A FIN DE FORMAR GRUPOS HIDROPEROXIDOS, Y EN LA IRRADIACION DE DICHA SUPERFICIE OZONIZADA CON LUZ ULTRAVIOLETA, O EN SU EXPOSICION AL CALOR PARA CONVERTIR LOS GRUPOS HIDROPEROXIDOS EN PORCIONES HIDROXILAS CON PRESENCIA DE UN DONANTE HIDROGENO. DICHAS SUPERIFICIES HIDROXILADAS POSEEN PROPIEDADES HIDROFILAS Y PUEDEN SUFRIR LAS REACCIONES QUIMICAS TIPICAS DE LOS GRUPOS HIDROXILOS. LOS POLIMEROS QUE SE HAYAN MODIFICADO DE ESTE MODO RESULTAN DE GRAN UTILIDAD EN DISPOSITIVOS BIOMEDICOS, MEMBRANAS SEMIPERMEABLES, PELICULAS, FIBRAS Y, EN ESPECIAL, LENTES DE CONTACTO.
