Abstract

PROCEDIMIENTO PARA LA PREPARACION DE POLIETERPOLIOLES. CONSTA DE LAS SIGUENTES ETAPAS: 1. ADICION AL POLIMERO ALCALINO DE UN 1 A UN 20 POR 100 EN PESO DE AGUA, ASI COMO DE 0 A UN 30 POR 100 EN PESO DE UN DISOLVENTE ORGANICO INERTE. 2 MANTENIMIENTO DE LA EMULSION FORMADA DURANTE UN TIEMPO DE MEDIA HORA A UNA TEMPERATURA MINIMA DE 70 C CON AGITACION MODERADA O SIN ELLA. 3. SEPARACION DE LA FASE ACUOSA. 4. SEPARACION DE LAS CANTIDADES RESUDULAES DE ALCALI DE LA FASE ORGANICA MEDIANTE DICION DE ACIDOS ABSORBENTES; EL DISOLVENTE ORGANICO Y EL AGUA RESUDUAL SE SEPARAN POR DESTILACION. EN LA TERCERA ETAPA LAS DOS FASES SE SEPARAN PASANDO LA EMULSION A TRAVES DE UNA ESTRUCTURA LAMINAR CONSTITUIDA POR FIBRAS DE METAL O MINERAL CON UN GROSOR ENTRE 1 Y 100 MM.,SIENDO LA VELOCIDAD DE FLUJO DE LA EMULSION A TRAVES DE LA ESTRUCTURA LAMINAR DE 1 A 20 M./H.
