Abstract

METODO PARA LA PREPARACION DE POLIESTIROL MEDIANTE POLIMERIZACION ANIONICA CONTINUA DE MONOMERO DE ESTIROL MEDIANTE UN CATALIZADOR A BASE DE UN ALQUILO METALICO, PREFERENTEMENTE EN PRESENCIA UN DISOLVENTE A UNA TEMPERATURA ENTRE 30 Y 70 (GRADOS) C, DE FORMA QUE EL MONOMERO DE ESTIROL SE CONDUCE A UN REACTOR DE CIRCULACION OPERADO ESENCIALMENTE DE FORMA ISOTERMICA Y CON TUBO QUE FORMA BUCLE DE RETROCESO EN SI MISMO, QUE PRESENTA POR EJEMPLO UNA SUPERFICIE REFRIGERANTE ESPECIFICA DE AL MENOS 50 M{SUP,2} POR M{SUP,3} DE VOLUMEN DE REACTOR; LA VELOCIDAD DE CIRCULACION DE LA MEZCLA DE REACCION Y EL TIEMPO DE ESTANCIA ESTAN AJUSTADOS DE MODO QUE EL GASTO DE MONOMERO LLEGA COMO MINIMO AL 50 % Y LA POLIMERIZACION TRANSCURRE HASTA EL FINAL EN UN REACTOR DE TUBO QUE OPERA ESENCIALMENTE SIN REMEZCLAS.
