FIELD: chemistry.
SUBSTANCE: method of producing super-absorbing polymer is proposed, including a) supplying a monomer for the composition containing (meth) acrylic acid and the polymerization initiator, thermal polymerization or photo-polymerization producing a polymer hydrogel b) drying the polymer hydrogel, c) milling the dried polymer hydrogel to a particle size of 150-850 microns, d) adding particles to the milled polymer hydrogel, characterized by i) a specific surface area according to BET method in the range of 300 to1500 m2/g and ii) a porosity constituting 50% or more, of the surface stapler, and e) conducting the reaction of the surface crosslinking.
EFFECT: proposed method allows to produce a super-absorbing polymer combining a high moisture content with an excellent processability.
