Abstract

SE PRESENTA UN METODO PARA PRODUCIR COMPOSICIONES POLIMERICAS ABSORBENTES EN PARTICULAS QUE CONTIENEN AGREGADOS ENLAZADOS DE INTERPARTICULAS. EN LOS METODOS DE LA INVENCION, SE APLICA UN ENLAZANTE DE INTERPARTICULAS SOBRE PARTICULAS PRECURSORAS; LAS PARTICULAS PRECURSORAS SE ASOCIAN FISICAMENTE PARA FORMAR UNA MULTIPLICIDAD DE AGREGADOS; Y EL AGENTE ENLAZANTE DE INTERPARTICULAS SE HACE REACCIONAR CON EL MATERIAL POLIMERO DE LAS PARTICULAS PRECURSORAS DE LOS AGREGADOS, MIENTRAS SE MANTIENE LA ASOCIACION FISICA DE LAS PARTICULAS PRECURSORAS, PARA FORMAR ENLACES ENTRE LAS PARTICULAS PRECURSORAS PARA FORMAR AGREGADOS ENLAZADOS DE INTERPARTICULAS. LOS AGREGADOS ENLAZADOS DE INTERPARTICULAS SE FORMAN HASTA UNA EXTENSION QUE EL TAMAÑO MEDIO DE LA PARTICULA DEL COMPUESTO POLIMERICO ES AL MENOS UN 25% MAYOR QUE EL TAMAÑO MEDIO DE LAS PARTICULAS DEL PRECURSOR.
