Abstract

SE PRESENTA UN REACTOR DE POLIMERIZACION ESTATICA CONTINUA PARA LA PREPARACION DE POLIMEROS LIQUIDOS QUE COMPRENDE UNA CAMARA DE REACCION HUECA Y ALARGADA (30) QUE TIENE UNA PARED POROSA (31) Y UNA CUBIERTA (40) SEPARADA ALREDEDOR DE LA CAMARA DE REACCION (30), QUE ESTA PROVISTA CON MEDIOS (44) PARA INTRODUCIR UN FLUIDO A TRAVES DE LA PARED POROSA (31). EL REACTOR ES PARTICULARMENTE UTIL PARA UN PROCESO PARA FABRICAR POLIMEROS LIQUIDOS CONDENSANDO MONOMEROS Y / O OLIGOMEROS. EL PROCESO COMPRENDE EL USO DE UN GAS A PRESION PARA PROVOCAR QUE LA MEZCLA DE REACCION ALCANCE UNA CONSISTENCIA SIMILAR A LA ESPUMA. ELLO ES BENEFICIOSO EN LA POLIMERIZACION DE CONDENSACION. LA ALIMENTACION DE UN FLUIDO A TRAVES DE LA PARED POROSA AL INTERIOR DE LA CAMARA DE REACCION EVITA LA CONSTRUCCION DEL POLIMERO SOBRE LA PARED.
