Abstract

Water-swellable, water-insoluble, ampholytic, hydrophilic polymers containing, in the polymerised state, in molar proportions, from 0.001 to 0.1 % of a water-soluble diethylenic crosslinking monomer and from 99.999 to 99.9 % of a mixture of 1 to 99% of N,N-dimethylaminoethyl acrylate in salt or quaternised form and from 99 to 1 % of a mixture, denoted M, of 1 to 99 % of acrylic acid and of 99 to 1 % of sodium acrylate or potassium acrylate, process for preparation and use as absorbent agent for aqueous fluids containing inorganic salts.
