Abstract

SE PRESENTAN MACROESTRUCTURAS POLIMERICAS, ABSORBENTES (52) QUE SON POROSAS Y QUE COMPRENDEN UN AGREGADO ENLAZADO DE INTERPARTICULAS QUE TIENE UN VOLUMEN CIRCUNSCRITO EN SECO MAYOR DE ALREDEDOR DE 10.0 MILIMETROS CUBICOS. EL AGREGADO ENLAZADO DE INTERPARTICULAS COMPRENDE UNA MULTIPLICIDAD DE PARTICULAS PRECURSORAS DE UN MATERIAL POLIMERO, FORMADOR DE UN HIDROGEL, ABSORBENTE, SUBSTANCIALMENTE INSOLUBLE EN AGUA; Y UN AGENTE ENLAZADOR DE INTERPARTICULAS QUE HA REACCIONADO CON EL MATERIAL DE POLIMERO DE LAS PARTICULAS PRECURSORAS PARA FORMAR ENLACES ENTRE LAS PARTICULAS PRECURSORAS. A CAUSA DE LA FORMA DE PARTICULA DE LAS PARTICULAS PRECURSORAS, LA MACROESTRUCTURA (52) TIENE POROS ENTRE PARTICULAS PRECURSORAS ADYACENTES. LOS POROS ESTAN INTERCONECTADOS POR CANALES DE INTERCOMUNICACION DE FORMA QUE LA MACROESTRUCTURA ES PERMEABLE A LOS LIQUIDOS.
