Abstract

UN METODO PARA LA PRODUCCION DE PARTICULAS COLOREADAS MICROFINAS QUE SE CARACTERIZA PORQUE SE SOMETE UN MONOMERO POLIMERICO SUSPENDIDO EN UNA SUSPENSION A UNA POLIMERIZACION DE SUSPENSION ANTE LA PRESENCIA DE UN AGENTE COLOREADOR Y/O UN POLVO MAGNETICO FORMANDO ASI PARTICULAS COLOREADORAS GLOBULARES MICROFINAS QUE TIENE UN DIAMETRO DE PARTICULA MEDIO QUE VA DE 3 A 50 (MU)M, TRATAR MEDIANTE CALOR DICHAS PARTICULAS COLOREADAS GLOBULARES MICROFINAS CON AGUA COMO MEDIO DE CALENTAMIENTO A UNA TEMPERATURA QUE OSCILA ENTRE LOS 50 (GRADOS) C Y LOS 130 (GRADOS) C INDUCIENDO ASI LA FUSION DE DICHAS PARTICULAS Y DANDO LUGAR A LA FORMACION DE BLOQUES DE PARTICULAS FUSIONADAS Y DESINTEGRAR DICHOS BLOQUES DE PARTICULAS A UN DIAMETRO DE PARTICULA MEDIO SUSTANCIALMENTE IGUAL AL DIAMETRO DE PARTICULA MEDIO DE DICHAS PARTICULAS COLOREADAS GLOBULARES MICROFINAS EXISTENTES ANTES DE DICHA FUSION.
