Abstract

<B>REDE POLIMéRICA DE POLIASPARTATO DE LIGAçãO CRUZADA E MéTODO PARA PRODUZIR A MESMA<D> Redes poliméricas super-absorventes de poliaspartatos de ligações cruzadas são produzidos de polisucinimida de ligações cruzadas. Redes poliméricas super-absorventes são produzidas em um vaso de reação única ao fazer vínculo cruzado de polisucinimida com pelo menos um agente de vínculo cruzado de poliamina orgânica na presença de pelo menos uma base nitrogenosa. A reação é realizada em uma mistura de reação aquosa para produzir uma rede polimérica de poliaspartato de vínculo cruzado.
