Abstract
Ageing of polymers was examined as a complex process taking place by a sole mechanism. The major role of free-radical reactions in this process was indicated. A study was made of the effect of molecular mobility of polymers on reaction kinetics in a polymer matrix. Results were examined of the three dimensional heterogeneity of reaction kinetics in polymers, which is related to structural heterogeneity (“kinetic interruption” of the reaction). Results were presented of a study of elementary reaction kinetics in polymers. A study was made of the relation between ageing kinetics and the variation of practically important properties of polymers. Mechanisms of stabilization of polymer materials were described and new principles of stabilization proposed. Data were given of an investigation into ageing kinetics of polymers under extremal conditions, by the action of UV light, in corrosive media and in tissues of living organism. Some problems of polymer combustion were discussed.
