Abstract

PROCEDIMIENTO PARA LA ELABORACION CONTINUA DE HOMO Y COPOLIOXIMETILENOS ESTABLES DE GRUPOS TERMINALES EN FASE HOMOGENEA, DONDE EN UN REACTOR TUBULAR SON POLIMERIZABLES CON ELEMENTOS ESTATICOS DE FORMALDEHIDO OLIGOMEROS CICLICOS EN PRESENCIA DE ACIDO PROTONICO COMO INICIADOR EN CANTIDAD DESDE 0,005 HASTA 500 PPM EN UNA ZONA DE POLIMERIZACION. EL TIEMPO DE PERMANENCIA DE LOS COMPONENTES DE REACCION EN ESTA ZONA ALCANZA DESDE 0,1 HASTA 10 MINUTOS Y A CONTINUACION DE FORMA INMEDIATA EN LA POLIMERIZACION SE REALIZA UNA DESACTIVIZACION DEL INICIADOR, CON LO CUAL SE DETERMINA UN PASO FLUIDO ENTRE ZONAS DE POLIMERIZACION Y DESACTIVACION, QUE ESTA CONDICIONADO UNICAMENTE A TRAVES DE LA ADICION DEL DESACTIVADOR, Y DONDE JUNTAMENTE A LA DESACTIVACION SE REALIZA UNA ESTABILIZACION DE LOS EXTREMOS DE CADENA EN PRESENCIA DE MONOMEROS RESIDUALES, DONDE EN UN AGREGADO DE DESGASIFICACION COLOCADO A CONTINUACION SE ELIMINAN LOS COMPONENTES VOLATILES A PARTIR DE LA MEZCLA DE REACCION. LA ESTABILIZACION SE REALIZA EN PRESENCIA DE SUSTANCIAS ALCALINAS, BIEN EN UNA TEMPERATURA DESDE 150 RESENCIA DE AGUA O BIEN CON ALCOHOLES PRIMARIOS O A UNA TEMPERATURA DESDE 175 ADICIONALES.
