Abstract

UN METODO PARA LA PRODUCCION DE MICROPARTICULAS DE UN POLIMERO TERMOPLASTICO ADECUADO COMO TONER PARA PROCESOS ELECTROSTATOGRAFICOS, QUE CONSISTE EN LOS PASOS SIGUIENTES: FUNDIR EL MATERIAL EN UNA FASE NO SOLVENTE CONTINUA QUE TENGA UN PUNTO DE EBULLICION MAYOR QUE EL PUNTO DE FUSION DEL POLIMERO TERMOPLASTICO, MEZCLAR EL POLIMERO TERMOPLASTICO EN LA FASE CONTINUA PARA OBTENER UNA EMULSION Y REFRIGERAR LA EMULSION PARA OBTENER UNA DISPERSION DE MICROPARTICULAS SOLIDAS DEL POLIMERO TERMOPLASTICO EN LA FASE CONTINUA. EL POLIMERO TERMOPLASTICO PUEDE INCLUIR PIGMENTOS O COLORANTES PARA LA OBTENCION DE PARTICULAS DE TONER COLOREADAS. SE PUEDE UTILIZAR UN AGENTE TENSIOACTIVO PARA CONTROLAR EL TAMAÑO DE LAS PARTICULAS.
