Abstract

EL PROCEDIMIENTO INCLUYE EN UN PRIMER ASPECTO LAS FASES DE: A) LA ALIMENTACION CONTINUA DE MONOMERO OLEFINICO Y UN SISTEMA CATALIZADOR DE UN COMPONENTE DE METALOCENO Y UN COMPONENTE COCATALIZADOR A UN REACTOR; B) LA POLIMERIZACION CONTINUA DEL MONOMERO EN EL REACTOR, A PRESION ELEVADA, EN UNA ZONA DE POLIMERIZACION; C) LA EXTRACCION CONTINUA DE UNA MEZCLA DE MONOMERO/POLIMERO DEL REACTOR; D) LA SEPARACION CONTINUA DEL MONOMERO DEL POLIMERO FUNDIDO, A UNA PRESION REDUCIDA; Y E) EL RECICLAMIENTO DEL MONOMERO SEPARADO AL REACTOR, CARACTERIZADO EN QUE: F) UN COMPONENTE VOLATIL ELIMINADOR DEL SISTEMA DEL CATALIZADOR, Y UN COMPONENTE NO VOLATIL ELIMINADOR DEL SISTEMA DEL CATALIZADOR, SE AÑADE EN LA DIRECCION DEL FLUJO DE LA CORRIENTE DE LA ZONA DE POLIMERIZACION, PARA ACTUAR RESPECTIVAMENTE EN LA SUPRESION DE LA POLIMERIZACION EN EL MONOMERO RECICLADO Y EL POLIMERO FUNDIDO SEPARADO. EN UN SEGUNDO ASPECTO DEL PROCEDIMIENTO ES BASICAMENTE LO MISMO, PERO SE AÑADE AGUA COMO UN COMPONENTE ELIMINADOR VOLATIL DEL SISTEMA DEL CATALIZADOR, EN LA DIRECCION DEL FLUJO DE LA CORRIENTE DE LA ZONA DE POLIMERIZACION, CON, PREFERENTEMENTE, UNA CANTIDAD DE AGUA QUE SE ESTA USANDO EN EXCESO Y QUE EXCEDE DEL NIVEL QUE SE NECESITA PARA ELIMINAR LOS COMPONENTES DEL SISTEMA DEL CATALIZADOR EN EL MONOMERO RECICLADO, Y CON UN COMPONENTE COCATALIZADOR QUE SE ESTA SUMINISTRANDO AL REACTOR, CAPAZ DE REACCIONAR CON EL MISMO EXCESO DE AGUA.
