Abstract

UN PROCEDIMIENTO EN EL CUAL SE FRACCIONA CAUCHO DE GUAYULE EN FRACCIONES DE PESO MOLECULAR PROMEDIO EN PESO CONVENIENTE. MEDIANTE UN SISTEMA DISOLVENTE. FRECUENTEMENTE SE UTILIZA UNA PLURALIDAD DE ETAPAS DE FRACCIONACION EN LAS CUALES LA FRACCION DE CAUCHO DE PESO MOLECULAR CONVENIENTE SE PRECIPITA O SE EXTRAE. LOS CAUCHOS DE ALTO PESO MOLECULAR PROMEDIO EN PESO, QUE TIENEN NORMALMENTE MENOS DEL 4, EN PESO DE CONTENIDO DE RESINA, SON EN GENERAL DESEABLES DEBIDO A SUS PROPIEDADES FISICAS FAVORABLES.
