Abstract

"POLìMEROS RETICULADOS, PULVERULENTOS, CAPAZES DE ABSORVER LìQUIDOS AQUOSOS". A invenção refere-se a polímeros reticulados, absorvíveis, à base de monómeros que portam grupos de ácidos, monoetilenicamente insaturados, parcialmente neutralizados, com propriedades aperfeiçoadas, especialmente com respeito à sua capacidade de transportar líquidos no estado intumescido, que foram pós-reticulados em sua superfície com uma combinação de um composto de reticulação orgânico com exceção dos polióis e com um cátion na forma de seu sal em uma solução aquosa.
