Abstract

PROCESSO PARA A PRODUçãO DE UM POLìMERO ABSORVENTE DE áGUA, E, POLìMERO ABSORVENTE DE áGUA. A presente invenção refere-se a um processo para a produção de polímero absorvente de água. De acordo com a invenção, um polímero base (A) que é produzido à base de um monómero inclusive grupos ácido até pelo menos <198> neutralizados é misturado com uma primeira solução aquosa (B) que contém pelo menos um agente reticulante secundário de superfície e com uma segunda solução aquosa (C) que contém pelo menos um cátion polivalente e é tratado termicamente. As soluções aquosas B e C são pelo menos parcialmente dosadas de uma maneira simultânea por meio de jatos separados. é obtido um polímero absorvente de água que tem alta capacidade de transmissão de fluído.
