Abstract

A physico-mathematical model describing kinetics of swelling of the polymer gels, which were
taken from water and immersed into water solutions, was suggested and experimentally confirmed. Kinetics
of swelling of KU-2x4 and KU-2x8 cationites in K-form and AB-17x8 anionites in Cl-form in KCl solutions
of different concentrations, as well as of cross-linked polyvinylic alcohol (PVA-20) in saccharose solutions
was studied. The influence of the polymer granular size on the swelling conditions was studied separately.
