Abstract

"COMPOSIçãO DE RESINA ABSORVENTE DE áGUA, ABSORVENTE, ARTIGO ABSORVENTE, MéTODO PARA PRODUZIR UMA COMPOSIçãO DE RESINA ABSORVENTE DE áGUA". Dito método da presente invenção para produzir uma composição de resina absorvente de água, cujo principal componente é uma resina particulada absorvente de água (A) possuindo uma estrutura de ligação cruzada obtida por meio de polimerização de um monómero não saturado contendo um grupo de ácido, dita resina particulada absorvente de água (A) sendo submetida a ligação cruzada nas proximidades de uma superfície da resina absorvente de água (A), no qual: a composição de resina absorvente de água contém 95% por peso ou mais de partículas cujo diâmetro de partícula é menor que 850 <109>m e no mínimo 106 <109>m e o diâmetro de partícula médio de peso das partículas é menor que 500 <109>m no mínimo 300 <109>m e um desvio padrão logarítmico (<sym><sym>) de distribuição de um tamanho de partícula da resina particulada absorvente de água (A) é de 0,45 ou menos e um componente solúvel em água da composição absorvente de água é de 35% por peso ou menos e a composição de resina absorvente de água inclui um componente metálico multivalente e uma taxa de extração do componente metálico multivalente é de 5,0% por peso ou mais e menos que 100% por peso. Assim, é possível obter a composição de resina absorvente de água, livre de qualquer coagulação de partículas em alta umidade, a qual possui uma propriedade absorvente superior em termos de absorvência e absorvência difusa sob pressão.
