Abstract

UN METODO PARA LA PREVENCION DE LOS PROBLEMAS DE ESTRATIFICACION EN UN REACTOR DE FASE GASEOSA EN DICHO PROCEDIMIENTO DE POLIMERIZACION MULTIFASICO, EL CUAL COMPRENDE AL MENOS UN REACTOR EN BUCLE SEGUIDO DE UN REACTOR DE FASE GASEOSA, DONDE LA POLIMERIZACION SE CONTINUA EN PRESENCIA DE MONOMEROS AÑADIDOS, UTILIZANDO EN EL PROCEDIMIENTO UN AGENTE ANTI-INCRUSTACION PARA EVITAR LA INCRUSTACION O LA ESTRATIFICACION EN LOS REACTORES. DE ACUERDO DON LA INVENCION, ENTRE EL 30 Y EL 70 % DEL PRODUCTO FINAL SE POLIMERIZA EN EL REACTOR EN BUCLE, DONDE SE AÑADE LA CANTIDAD TOTAL DEL AGENTE ANTI-INCRUSTACION, SIENDO LA CANTIDAD DEL AGENTE MAYOR DE LO NECESARIO PARA EVITAR LA INCRUSTACION EN EL REACTOR.
