FIELD: chemistry.
SUBSTANCE: claimed invention relates to method of obtaining water-absorbing polymer particles. Described is method of obtaining water-absorbing polymer particles, when formed are monomer-containing drops, which contain not less than one ethylene unsaturated monomer, which contains at least one acidic group, not less than one agent for formation of lattice structure, at least one initiator and water, monomers are polymerised in heated gas phase, which surrounds drops, and gas passes through polymerisation reactor, temperature of gas, leaving polymerisation reactor, is regulated, method is characterised by the fact that regulation is carried out by preliminary heating of passing through reactor gas by means of appropriate heat-exchanger before reactor input.
EFFECT: elaboration of method, which makes it possible to obtain water-absorbing polymer particles of constant high quality.
