Abstract

PROCESO PARA LA PRODUCCION DE POLIMEROS DE ESTIROL A TRAVES DE LA POLIMERIZACION CONTINUA, CON LO QUE EL O LOS MONOMEROS Y LOS COMPUESTOS ORGANOMETALICOS QUE SIRVEN COMO PARTIDA (INICIADOR) SON GUIADOS EN SOLUCION A UN REACTOR TUBULAR QUE TRABAJA ESENCIALMENTE LIBRE DE MEZCLA REPETIDA Y SE DEJAN EN SU SITIO PARA LA UTILIZACION DE LOS MONOMEROS EN EL REACTOR. LA POLIMERIZACION SE REALIZA AL MENOS EN DOS TRAMOS DE REACTOR FUNCIONANDO ESENCIALMENTE DE FORMA ADIABATICA SIGUIENDO UN TRAMO A OTRO CON AL MENOS UN INTERCAMBIADOR DE CALOR DISPUESTO ENTRE LOS TRAMOS INDICADOS. EVENTUALMENTE SE CONDUCE UNA CANTIDAD PARCIAL DEL INICIADOR DE PARTIDA Y/O DE LOS MONOMEROS AL REACTOR CONECTADO CON EL PRIMER REACTOR.
