Abstract

LA INVENCION SE REFIERE A UN METODO DE PRODUCCION DE POLIMEROS DE 2 - HIDROXI - ETIL - METACRILATO, QUE CONSISTE EN POLIMERIZAR 2 - HIDROXIETIL METACRILATO O UNA MEZCLA MONOMERICA DEL MISMO QUE CONTIENE UN COMPUESTO DE HALOGENO, MEDIANTE POLIMERIZACION RADICALAR; METODO DE PRODUCCION DE HIDROGELES, QUE CONSISTE EN SOMETER DICHOS POLIMEROS A UN TRATAMIENTO DE TRANSMISION DE AGUA; METODO DE PRODUCCION DE LENTES DE CONTACTO BLANDAS QUE CONTIENEN AGUA, CONSISTENTE EN MOLDEAR DICHOS POLIMEROS EN FORMA DE LENTES DE CONTACTO Y SOMETERLOS A UN TRATAMIENTO DE TRANSMISION DE AGUA. SE DESCRIBE ASIMISMO UN METODO DE PRODUCCION DE POLIMEROS CONSISTENTE EN TRATAR AL MENOS LAS SUPERFICIES DE MOLDEO DE LOS MOLDES, QUE FORMAN UNA CAVIDAD EN FORMA DE LENTE DE CONTACTO, CON UN COMPUESTO DE HALOGENO Y POLIMERIZAR 2 - HIDROXIETIL METACRILATO O UNA MEZCLA DE MONOMEROS DEL MISMO EN DICHA CAVIDAD, MEDIANTE POLIMERIZACION RADICALAR. SEGUN LA PRESENTE INVENCION, SE OBTIENEN LENTES DE CONTACTO BLANDAS QUE CONTIENEN AGUA CON ELEVADA TERMORRESISTENCIA E INTERMEDIARIOS DE LAS MISMAS, A PARTIR DE 2 - HIDROXIETIL METACRILATO DE ELEVADA PUREZA.
