摘要：

The kinetics of the contraction of a highly swollen polyelectrolyte hydrogel under the influence of electric current was investigated. From the results obtained, different mechanisms of the contraction may be supposed to predominate for different degrees of swelling. In the case of a rather small contraction, it depends only on the magnitude of electric charge transported through the sample and is described by the Faraday law with the correction coefficient. The second mechanism may be connected with electro-osmotic release of water.
