Abstract

Patente de Invenção: <B>"COMPOSIçãO DE ABSORçãO DE áGUA E O USO DA MESMA"<D>. A presente invenção proporciona: uma composição de absorção de água de modo que as partes que contêm a composição de absorção de água em alta concentração exibem efeitos de tamponamento de permeação de líquido excessivo em artigos absorventes compreendem a composição de absorção de água e fibras hidrófilas; e ao uso da referida composição de absorção de água. A composição de absorção de água compreende uma resina de absorção de água e um tampão de permeação de líquido excessivo, onde a resina de absorção de água é um produto do processo que inclui a etapa de adicionalmente reticular as vizinhanças da superfície do polímero reticulado, e a referida composição de absorção de água é caracterizada por ter um índice de tamponamento de permeação de líquido não inferior a 0,4 e exibir uma capacidade de absorção não inferior a 25 g/g nas estruturas absorventes sob carga, e adicionalmente ter um diâmetro médio de partícula na faixa de 200 - 600 <109>m, onde a proporção de partículas dotadas de diâmetro de partícula inferior a 106 <109>m na composição de absorção de água é, não é mais de 5% em peso. A referida composição de absorção de água é, por exemplo, usada para artigos absorventes que compreendem a composição de absorção de água e fibras hidrófilas.
