## Abstract A facile, electrically induced reversible gelation in a PAA aqueous solution containing Fe ions has been realized. The PAA solution is converted into a homogeneous hydrogel when the ferrous ions are electro‐oxidized to ferric ions and this gel is restored to solution by electro‐reductio

Conductimetry was used for monitoring the radical polymerization of a weak electrolyte (acrylic acid) in aqueous solution and for determination of the kinetic parameters of the reaction (reaction order with respect to monomer, activation energy). The results obtained were consistent with those deter
## Abstract The radical polymerization of acrylic acid in the presence of poly(vinyl alcohol) as a template in aqueous solution has been studied using conductimetry, which shows template influences on the reaction rate. A comparison is made between data obtained by differential scanning calorimetry
