Abstract

"POLìMEROS EM FORMA DE Pó, RETICULADOS NA SUPERFìCIE". A presente invenção refere-se a um polímero em forma de pó, reticulado complementarmente na superfície, absorvedor de água ou líquidos aquosos, formado de monómeros polimerizados, opcionalmente reticulados previamente, que contêm grupos carboxila, parcialmente neutralizados. A presente invenção refere-se, além disso, a um processo para tratamento complementar dos polímeros acima citados e ao uso de uma solução de pelo menos um sal de um cátion pelo menos trivalente, para restauração da permeabilidade de gel dos referidos polímeros, que tenham sido danificados por ação mecânica.
