Abstract
"COMPOSIçãO ABSORVENTE". é descrita uma composiçãoabsorvente compreendendo um material ácido e um materialbásico, onde a composição absorvente exibe propriedadesabsorventes desejáveis. Especialmente, a presente invençãorefere-se a uma composição absorvente compreendendo tanto umpolímero solúvel em água ácida, polímero insolúvel a águapossuindo pK~ a~ entre aproximadamente 2 e aproximadamente12 ou um polímero solúvel em água ácida, polímero insolúvel aágua possuindo um pK~ b~ entre aproximadamente 2 eaproximadamente 12 e tanto um segundo material ácido ou umsegundo material básico. A composição absorvente possui ahabilidade para absorver lentamente um grande quantidade deliquido, particularmente quando sob uma pressão externa. Acomposição absorvente ser útil em produtos absorventesvendíveis, tais como estes produtos absorventes vendíveis quesão utilizados para absorver líquidos corpóreos.
