Abstract

<B>GELS SUPERABSORVENTES COM BASE EM POLI(VINILAMINA), E MéTODO PARA MANUFATURAR O MESMO<D> São revelados gels superabsorventes com base em poli(vinilamina). Os gels superabsorventes compreendem uma mistura de um polímero de poli(vinilamina) e um polímero ácido absorvente de água, como o ácido poliacrílico, ou então compreende um sal de um polímero poli(vinilamina). Também são revelados um método melhorado de preparar o poli(vinilamina), e núcleos de fraldas melhorados.
