In connection with the study of polymer redox catalysts, the properties of condensation products of hydroquinone with chloromethylated styrene-divinylbenzene copolymers have been examined in more detail. It was found that only part of the hydroquinone bonded is capable of electron exchange in aqueous medium and only this part is likely catalytically active for reaction in gaseous phase. The effect of reagents and temperature during preparation of polymers containing hydroquinone functional groups leads to destruction of macromolecules to form carbon clusters which have the same catalytic activity as functional hydroquinone groups. Only part of these clusters is, however, capable of electron exchange in aqueous medium. The higher the catalytic activity, the lower the thermal stability of the polymer.
