In the framework of the mean-field theory for the order parameter, which characterizes the degree of deviating the structure of a network-like macromolecule from its natural state under the action of the external force, its mechanical hysteresis is considered. Elastic hysterical properties of a macromolecule are studied as a function of the applied force, temperature and some other parameters controlling the viscous-elastic behavior of network-like macromolecules.
