Abstract

SE DESCRIBE UN PROCESO PARA LA PRODUCCION DE UN POLICARBONATO AROMATICO QUE TIENE UNA FORMA EMULSIONADA AGUA-EN-ACEITE Y UNA ESTABILIDAD TERMICA MEJORADA DURANTE EL MOLDEADO A UNA TEMPERATURA ELEVADA. SEGUN LA INVENCION, DURANTE EL PROCESO SE AÑADE UNA AMINA TERCIARIA A LA EMULSION DE AGUA-EN-ACEITE DESPUES DE HABERSE REDUCIDO EL DIAMETRO MEDIO DE LAS GOTITAS LIQUIDAS DE LA FASE DE AGUA A NO MAS DE 10 (MU)M. EL POLICARBONATO DETENIDO SEGUN EL PROCESO DE LA INVENCION TIENE UNA ESTABILIDAD TERMICA MEJORADA Y PUEDE PROPORCIONAR UN ARTICULO MOLDEADO CON MENOS COLORACION.
