Abstract

METODO PARA LA OBTENCION DE UN COPOLIMERO RETICULADO E HIDROFILO DE ACRILATO DE 2-HIDROXIETILO Y DE UN ACRILATO DE ALCOHILO. SE MEZCLA ACRILATO DE 2-HIDROXIETILO CON UN ACRILATO DE ALCOHILO EN UN DISOLVENTE ORGANICO SOLUBLE EN AGUA, EN PRESENCIA DE UN AGENTE DE RETICULACION Y DE UN INICIADOR DE RADICALES LIBRES. DICHA SOLUCION ES PUESTA EN UN MOLDE HERMETICAMENTE CERRADO, DONDE LOS MONOMEROS SON SOMETIDOS A POLIMERIZACION Y RETICULACION, BAJO TEMPERATURA CONTROLADA. A CONTINUACION SE EFECTUA EL CURADO Y EL POSTERIOR DESMOLDEO DEL COPOLIMERO RESULTANTE. FINALMENTE SE EXTRAEN LOS RESIDUOS Y LOS DISOLVENTES EXISTENTES EN DICHO COPOLIMERO MEDIANTE INTERCAMBIO CON UNA SOLUCION ACUOSA. COMO ACRILATO DE ALCOHILO SE EMPLEA PREFERENTEMENTE UNO DE LOS SIGUIENTES COMPUESTOS: ACRILATO DE METILO, ACRILATO DE ETILO, ACRILATO DE PROPILO, ACRILATO DE BUTILO Y ACRILATO DE PENTILO. EL COPOLIMERO OBTENIDO ES DE EMPLEO EN CIRUGIA OFTALMOLOGICA Y EN LA FABRICACION DE LENTES DE CONTACTO.
