A B S T R A C T A powdery absorbing material for aqueous liquids based on a water-swellable powdery polymer with at least 0.2 equivalents carboxyl groups per 100 parts by weight which are neu- tralized by 50 to 99, advantageously by at least 80 mol-%. The absorbent is obtained by treating the wa- ter-swellable carboxyl-groups-containing polymer with a solution of an N-(hydroxyalkyl).beta.-(meth)-alanine es- ter or with the polycondensation products thereof. As solvent for the agent water is used which either com- prises water-miscible organic diluents evaporating on heating the mixture, or non-evaporating ones, i.e., diluents remaining in the polymer.
