Abstract

The invention relates to a superabsorbent polymer based on a cross-linked acrylic polymer derivative, in which the content of acrylic polymer containing a N atom, such as acrylamide or acrylonitrile, represents between 5 % and 95 % by weight, said superabsorbent comprising at least a hydrocolloidal polysaccharide in a amount not exceeding 5 parts by weight for 100 parts of acrylic units.
