Abstract

PROCEDIMIENTO PARA LA PREPARACION DE POLIPROPILENO POROSO EN FORMA DE POLVO. SE ENFRIAN EN EL MARGEN DE 260-120 C. AN UNA VELOCIDAD DE 2 A 10 C, POR MINUTO, SOLUCIONES CALIENTES DE PROPILENO, QUE PUEDEN TENER HASTA 10 POR 100 DE OLIETILENO, EN UN ESTER DE PENTAERITRITA CON UNA PROPORCION DE POLIPROPILENO: PENTAERITRITA DE 25: 75 A 15: 85, HASTA LA TEMPERATURA AMBIENTE. SE TRITURA DE FORMA MECANICA LA MASA SOLIDIFICADA Y SE EXTRAE CON UN DISOLVENTE, EN EL QUE ES SOLUBLE EL ESTER DE PENTAERITRITA, ELIMINANDOSE POSTERIORMENTE EL DISOLVENTE DE MANERA AMPLIA. SE UTILIZA PARA LA SEPARACION DE SUSTANCIAS HIDROFOBAS, ESPECIALMENTE ACEITES, A PARTIR DE SISTEMAS ACUOSOS, ASI COMO PARA LA ABSORCION DE LIQUIDOS.
