    Abstract: Superabsorbent material, comprising first superabsorbent polymers, coated with second clay-crosslinked superabsorbent polymers, said second clay-crosslinked superabsorbent polymers being obtainable by the step of polymerization of a solution/dispersion of polymerizable compounds and clay particles, to obtain said second superabsorbent polymers, crosslinked by said clay particles, of a weight average largest particle dimension of less than 800 nm.
