Abstract
AGENTE PARTICULADO ABSORVENTE D'áGUA COM RESINA ABSORVENTE D'áGUA COMO COMPONENTE PRINCIPAL A presente invenção fornece um agente de absorção d'água que mantém excelentes propriedades de absorção d'água por um longo período, mesmo quando a composição da urina humana varia. Um agente de absorção d'água particulado compreendendo uma resina de absorção d'água obtida através de polimerização por entrecruzamento de um monómero insaturado, o qual exibe capacidade de retenção centrífuga em uma solução salina fisiológica de não menos que 32 g/g, tamanho médio de partícula ponderal (D~ 50~) de 200 <109>m, a 400 <109>m proporção de partículas com diâmetro menor que 150 <109>m de 0% a 2% em peso, e extraíveis aumentados por deterioração de 0 a 15% em peso e extraíveis por uma hora em líquido de teste de deterioração de 0,1 a 30% em peso.
