ABSTRACT
Processes of rubber aging in the different kinetic modes and mathematical models of the processes including aging and destruction processes under extreme conditions are studied. The aging process for rubbers as thermodynamically open nonlinear systems is considered. It was revealed that the aging process can be controlled by means of the internal physical and chemical processes organization and by creation of external influences (by the organization of thermodynamic forces and streams). According to the Onsager principle, in certain conditions of aging the conjugation of thermodynamic forces and streams is possible. The diffusion and structural aspects of aging of elastomeric rubbers and articles thereof are considered. The composite antiaging systems of prolonged action based on the use of microparticles with a saturated solution of the antiagers migrating into an elastomeric matrix at the exploitation are proposed.
