Abstract
En un método para eliminar monómeros sin reaccionar y otras materias volátiles de una composición de disolución de polímero producida por polimerización en masa continua o polimerización en disolución continua de un monómero vinílico aromático en solitario o de una mezcla de un monómero vinílico aromático y otros monómeros copolimerizables con dicho monómero aromático en presencia o ausencia de polímeros tipo caucho, un método para eliminar materias volátiles de una composición de disolución de polímero que comprende efectuar la eliminación de materias volátiles en múltiples fases con el uso de dos o más recipientes de desgasificación súbita, ajustar el contenido en sólido de la composición de disolución de polímero a la salida del desgasificador previo al desgasificador de la última fase hasta un nivel en exceso de 97%, añadir 0,5-4% en peso de un agente espumante a la composición de disolución de polímero total durante la transferencia de dicha composición desde la salida del desgasificador anterior al desgasificador de la última fase hasta la entrada del desgasificador de la última fase, hacer pasar dicha composición desde la entrada del desgasificador de la última fase hasta un controlador de presión mientras se mantiene la presión de dicha composición a 10 kg/cm2 o más mediante el controlador de presión dispuesto dentro del desgasificador de la última fase o a la entrada del desgasificador de la última fase y mantener la temperatura de dicha composición en el intervalo 190-260ºC, después de ello, introducir la composición de disolución de polímero en un recipiente de separación vapor-líquido mantenido a un vacío de 20 Torr o menos y permitir a dicha composición espumar.
