Abstract
"FIBRA SUPERABSORVENTE DE MULTICOMPONENTES,ARTIGO, MéTODO PARA ABSORVER UM MEIO AQUOSO,MATERIAL SUPERABSORVENTE, E, MéTODO PARAFABRICAR UMA FIBRA SUPERABSORVENTE DEMULTICOMPONENTES". Fibras superabsorventes demulticomponentes são divulgadas. As fibras de multicomponentescompreendem pelo menos uma resina ácida que absorve água epelo menos uma resina básica que absorve água. Cada fibracontém pelo menos um microdomínio da resina ácida em contatoou em proximidade íntima, com pelo menos um microdomínio daresina básica. Combinações de fibras superabsorventes demulticomponentes com partículas de uma segunda resina queabsorve água também são divulgadas. Artigos contendo as fibrassuperabsorventes de multicomponentes também são divulgados.
