Abstract

LA INVENCION TRATA DE UN PROCEDIMIENTO PARA LA SEPARACION DE HETEROPOLICOMPUESTOS A PARTIR DE MEZCLAS QUE CONTIENEN POLIMEROS, COMO POLIETERES, POLIESTERES Y/O ESTERES DE POLIETER, UN COMPONENTE PROTICO Y HETEROPOLICOMPUESTOS, QUE SE CARACTERIZA PORQUE EL COMPONENTE PROTICO SE RETIRA DE LA MEZCLA Y EL HETEROPOLICOMPUESTO SE SEPARA DESPUES COMO FASE SEPARADA. LA FASE POLIMERICA RESTANTE PREFERENTEMENTE SE PONE EN CONTACTO CON UN ADSORBENTE SOLIDO, QUE PUEDA ADSORBER LOS HETEROPOLICOMPUESTOS.
