Jumping Exothermic Effect in Polymer Gels

The specific reaction of polymer gels to the effect of an alternating temperature field is explored that is manifested in an exothermic effect, the position of which on the temperature scale depends on the thermal prehistory of the gel. It is found that the described exothermic effect is observed in polymer gels of any nature, and for its manifestation it is necessary to have a spatial network structure in which both free and bound solvent molecules are present.
