Abstract

PROCEDIENTO DE PRODUCCION DE MICROCAPSULAS POR POLIMERAZACION DE MELAMINA Y FORMALDEHIDO. SE PREPARA UNA SOLUCION ACUOSA DE UN POLIMERO SOLUBLE EN AGUA, SE EMULSIONA Y SE DISPERSA EL LIQUIDO OLEOSO HIDROFOBO QUE DESA ENCAPSULAR, SE LE AGREGA UN ISOCIANATO POLIVALENTE Y UN ISOTINIATO POLIVAALENTE EN COMBINACION CON LA ANTERIOR SOLUCION ACUOSA. SE LE AÑADE UNA SOLUCION ACUOSA DE MELAMINA Y FORMALDEHIDO Y SE FORMAN LAS PAREDES DE LAS CAPSULAS PROVOCANDO UNA POLICONDENSACION DE LA MELAMINA Y DEL FORMALDEHIDO POR AGITACION Y ELEVACION DE TEMPERATURA.
