Abstract

"POLìMERO RETICULADO, PROCESSO PARA SUA PRODUçãO, ESTRUTURA E ARTIGO ABSORVENTE E FRALDA DE PAPEL". Um polímero reticulado (A) que compreende, como unidades estruturais essenciais, unidades derivadas de (a) um ou mais monómeros de vinila selecionados do grupo consistindo de monómeros de vinila solúveis em água e/ou monómeros de vinila que se tornam solúveis em água mediante hidrólise e unidades derivadas de (b) um agente reticulante, e que satisfaz os seguintes requisitos: (1) (X) <242> 25 g/g, (2) (Y) <242> 15 g/g e (3) (Y) <242> 0,54 (X) + 41. Ele possui retenção hídrica extraordinariamente alta e poder de absorção sob carga extraordinariamente elevado. Quando aplicado numa estrutura absorvente e num artigo absorvente, o polímero apresenta excelente desempenho de absorção. Nas relações, (X) é a quantidade de solução salina fisiológica retida ao longo de 1 hora de absorção e (Y) é a quantidade de solução salina fisiológica absorvida ao longo de 1 hora de repouso sob uma carga de 60g/cm^ 2^.
