Abstract

Un proceso para preparar una composición super- absorbente de poliamida, que comprende: I) poner en contacto una pasta de celulosa deshidratada con una solución de una composición de polisuccin-imida (PSI) reticulable, no reticulada, parcialmente hidrolizada e internamente plastificada para producir una composición de pasta de celulosa al menos parcialmente recubierta, y II) secar dicha composición de pasta de celulosa al menos parcialmente recubierta en condiciones de reticulación para reticular una porción de los grupos succinimida no reticulados en dicha composición de PSI y formar la composición superabsorbente de poliamida.
