Abstract

LA PRESENTE INVENCION PRESENTA MATERIALES SUPERABSORBENTES CON FORMA DE LAMINAS O FIBRAS HECHAS A PARTIR DE POLIMEROS QUE SE PUEDEN DERRETIR EN GRAN MEDIDA Y QUE TIENE UN MATERIAL DE POLIMERO SUPERABSORBENTE DISPERSADO UNIFORMEMENTE A SU TRAVES. LOS MATERIALES SON CAPACES DE RECIBIR GRANDES CANTIDADES DE POLIMEROS SUPERABSORBENTES LO QUE DA COMO RESULTADO UNAS PROPIEDADES DE RETENCION Y ABSORBENCIA SUSTANCIALMENTE MEJORADAS.
