Abstract

SE PROPORCIONA UN METODO PARA POLIMERIZACION DE MASA CONTINUA DE TERMOPLASTICOS TIPO ACRILONITRILO-BUTADIENO-ESTIRENO. EL METODO SUPONE CARGAR UN ALIMENTO LIQUIDO QUE COMPRENDE UN MONOMERO AROMATICO DE VINIL-IDENO, UN MONOMERO NO SATURADO DE VINIL-NITRILO Y UN POLIMERO SINTETICO DE BUTADIENO DISUELTO EN UN REACTOR DE UNION PARA PRE-REACCIONAR LA MASA LIQUIDA CON EL FIN DE FORMAR PRODUCTOS POLIMERICOS DE FASE CONTINUA DE CAUCHO INJERTADO. EL PRODUCTO DEL REACTOR DE UNION SE CARGA EN UN REACTOR DE INVERSION DE FASE DONDE EL COPOLIMERO RIGIDO LIBRE EN EL MONOMERO ES LA UNICA FASE CONTINUA, Y DONDE LAS PARTICULAS DISPERSAS DE CAUCHO INJERTADO CON MONOMERO Y COPOLIMERO RIGIDO OCLUIDO SE FORMAN INMEDIATAMENTE DEL PRODUCTO DEL REACTOR DE UNION. EL SEGUNDO PRODUCTO DE POLIMERIZACION, QUE VA SALIENDO DEL REACTOR DE INVERSION DE FASE, SE CARGA ENTONCES A UN REACTOR DE FINALIZACION DONDE EL MATERIAL ADEMAS SE POLIMERIZA PARA FORMAR UN TERCER PRODUCTO DE POLIMERIZACION QUE ENTONCES SE PUEDE VOLATILIZARPARA PROPORCIONAR UNA COMPOSICION TERMOPLASTICA FINAL. EL PROCESO DEL PRESENTE INVENTO PROPORCIONA CAPACIDAD Y FLEXIBILIDAD UNICAS PARA CONTROLAR Y AJUSTAR EL INJERTO DE CAUCHO Y LA MORFOLOGIA DE LAS PARTICULAS DE CAUCHO. LAS CONDICIONES DEL PROCESO SE PUEDEN CONTROLAR PARA PRODUCIR UN PRODUCTO DE RESINA DE BRILLO ELEVADO O BAJO.
