Аннотация:Temperature was shown to substantially influence the swelling of KB2e3 polyacrylic and
KB4P2 polymethacrylic ionites crosslinked by triethylene glycol dimethacrylate (TEGDM) and divi
nylbenzene (DVB). Maximum swelling changes as the temperature increased were observed for the Ca
form of the KB4P2 ionite. Swelling and contraction of polymethacrylic cationite grains as the temper
ature decreased and increased occurred at equal fairly high rates, whereas the sorption of water by the
polyacrylic cationite in the calcium form crosslinked by TEGDM occurred much more slowly than
desorption.
