Abstract

SE MUESTRAN MACROESTRUCTURAS POLIMERICAS,FLEXIBLES, POROSAS Y ABORBENTES QUE TIENEN FLEXIBILIDAD INCLUSO DESPUES DE PERIODOS EXTENSOS DE TIEMPO A ELEVADAS TEMPERATURAS Y/O BAJAS HUMEDADES. LA MACROESTRUCTURA CONSTA DE UN AGREGADO RETICULADO INTERPARTICULAR Y UNA CANTIDAD SUFICIENTE DE UN PLASTIFICADOR ADECUADO. LAS MACROESTRUCTURAS ESTAN INDICADAS PARA USAR, POR EJEMPLO, EN ARTICULOS ABSORBENTES DESECHABLES COMO PUEDEN SER LOS PAÑALES.
