Abstract

PROCEDIMIENTO PARA LA ELABORACION DE POLIETERPOLIOLES. CONSTA DE LAS SIGUENTES ETAPAS 1. ADICION AL POLIMERO ALCALINO DE ACIDOS Y DE UN 1 A UN 30 POR 100 EN PESO DE AGUA, DEMAS DE UN 0 A 30 POR 100 DE UN DISOLVENTE ORGANICO INERTE. 2. LA EMULSION FORMADA DE AGUA EN ACEITE SE CALIENTE A UNA TEMPERATURA DE AL MENOS 70 C.3. LA FASE ACUOSA SE SOMETE A ACOALESCENCIA Y A CONTUNIACION SE SEPARA DE LA FASE ORGANICA. 4. EL AGUA RESIDUAL, ASI COMO EL DISOLVENTE ORGANICO SE SEPARAN POR DESTILACION, SEPARANDO LA SAL RESUDUAL POR FILTRANCION. EL POLIETER EN BRUTO SE NEUTRALIZA A UN PH DE APROXIMADAMENTE 4 A 9. EN LAS EGUNDA ETAPA, LA EMULSION SE CALIENTA AL MENOS A 85. EN LA TERCERA ETAPA LA FASE ACUOSA SE COALIZA CONDUCIENDO LA EMULSION A TRAVES DE UNA ESTRUCTURA LAMINAR.
