Abstract

"COMPOSIçãO DE RESINA ABSORVENTE DE áGUA PARTICULADA E SEU PROCESSO DE PRODUçãO". Um objetivo da presente invenção é fornecer uma composição de resina absorvente de água particulada e seu processo de produção, onde a composição de resina absorvente de água particulada é aperfeiçoada em ambas 'permeabilidade de líquido' e 'propriedade de absorção de líquido' (que tem sido até agora propriedades físicas antitéticas) da resina absorvente de água. Como um meio de alcançar esse objetivo, uma primeira composição de resina absorvente de água particulada de acordo com a presente invenção e uma composição de resina absorvente de água particulada compreendendo uma resina absorvente de água (A) de uma estrutura reticulada obtida por polimerização de um monómero insaturado contendo grupo de ácido, com a composição sendo caracterizada por: ter um tamanho de partícula tal que as partículas na faixa de 850 a 150 um (porém não incluindo 850 um) sejam responsáveis por não menos do que 90% em peso do total; e contendo um poliol tetra- ou mais funcional (B) pelo menos sobre as superfícies.
