Abstract

SE DESCRIBE UN PROCESO PARA PURIFICAR POLIMEROS SEPARANDO Y ELIMINANDO LOS COMPONENTES VOLATILES DE UNA COMPOSICION POLIMERICA QUE CONTIENE TALES COMPONENTES, QUE COMPRENDE: (A) UN PASO DE CALENTAR LA COMPOSICION POLIMERICA QUE CONTIENE UN DISOLVENTE TAL COMO METANOL A UNA TEMPERATURA DE 120-270 C; (B) UN PASO DE DESCARGAR LA COMPOSICION POLIMERICA EN UN TANQUE QUE SE MANTIENE A UN DETERMINADA PRESION, Y ENTONCES SEPARAR Y RECOGER MUCHOS DE LOS COMPONENTES VOLATILES DE LA COMPOSICION; Y (C) UN PASO DE SUMINISTRAR LA COMPOSICION POLIMERICA OBTENIDA A UN EXTRUSOR DE VENTILACION EN EL QUE SE AJUSTA UNA PREDETERMINADA TEMPERATURA, Y A UNA ZONA DE VENTILACION QUE SE AJUSTA A UNA PRESION PREDETERMINADA, Y ENTONCES SE EXTRUYE PARA DISMINUIR EL CONTENIDO DE COMPONENTES VOLATILES RESTANTES EN LA COMPOSICION HASTA UN 1% EN PESO O MENOS. ALTERNATIVAMENTE, SI ES NECESARIO, ENTRE LOS PASOS (B) Y (C) YA MENCIONADOS SE PUEDE INTERPONER UN PASO (B'') PARA INTRODUCIR UN GAS INERTE EN LA COMPOSICION POLIMERICA ANTES O DURANTE EL CALENTAMIENTO, O EN LA PROXIMIDAD DE LA COMPOSICION POLIMERICA QUE ESTA SIENDO DESCARGADA DENTRO DEL TANQUE. DE ACUERDO CON ESTE PROCESO, EL POLIMERO PUEDE SER SEPARADO Y PURIFICADO FACILMENTE, DE FORMA QUE EL POLIMERO DE ALTA CALIDAD, PARTICULARMENTE EL POLIMERO DE METIL METACRILATO PUEDE FABRICARSE EFICIENTEMENTE SIN IMPLICAR MODIFICACION TAL COMO LA COLORACION.
