Abstract

SE DESCRIBE UN PROCEDIMIENTO PARA PRODUCIR UNA PELICULA MICROPOROSA POLIHALOGENADA, QUE TIENE UNA DISTRIBUCION DE TAMAÑO DE PORO MUY ESTRECHA Y BUENA RESISTENCIA QUIMICA Y A LA TEMPERATURA. EL PROCEDIMIENTO CONSISTE EN MEZCLAR UN COPOLIMERO POLIHALOGENADO, QUE TIENE UN TAMAÑO DE PARTICULA MUY PEQUEÑO, CON UN POLIMERO LIGANTE, UTILIZANDO UN DISOLVENTE, QUE NO ES DISOLVENTE DEL COPOLIMERO POLIHALOGENADO, PERO DISUELVE EL POLIMERO LIGANTE, FORMAR UNA PELICULA A PARTIR DE LA MEZCLA, SECARLA, CALENTARLA A UNA TEMPERATURA IGUAL O SUPERIOR AL PUNTO DE FUSION DEL COPOLIMERO POLIHALOGENADO, Y EN CONDICIONES TALES QUE LAS PARTICULAS MICROPARTICULADAS Y SUS PUNTOS DE CONTACTO MUTUO ESTEN JUNTOS PARA FORMAR UNA MATRIZ RELATIVAMENTE CONTINUA, Y EXTRAER EL POLIMERO LIGANTE DE LA PELICULA UTILIZANDO UN DISOLVENTE DE LA PELICULA LIGANTE, PARA FORMAR UNA PELICULA MICROPOROSA.
