Abstract

LA PRESENTE INVENCION SE REFIERE A UN PROCEDIMIENTO PARA EL AISLAMIENTO DE POLIMEROS DE SUS DISOLVENTES POR MEDIO DE LA ADICION DE FLUIDOS QUE CONTENGAN DIOXIDO DE CARBONO EN TEMPERATURAS DE 30 A 280 C Y PRESIONES DE 1 BAR HASTA 1000 BARES Y QUE SE CARACTERIZA POR QUE LA CONCENTRACION DE POLIMEROS EN SUS DISOLVENTES ES, RESPECTIVAMENTE, DE ENTRE UN 5 A UN 80% DEL PESO Y EL FLUIDO QUE CONTIENE DIOXIDO DE CARBONO SE COMPONE DE AL MENOS UN 50% DEL PESO DE DIOXIDO DE CARBONO.
