Inhoud: Principles of kinetic model composition of initiated free radical transformations in an amorphous polymer matrix are discussed. Micellar-sponge model of supermolecular structure which takes into account character of inhomogeneous zone functioning different by sizes and fluctuation dynamics of micropores composing them are put to the base of the chemical modelling. Features of antioxidant effects on chain processes are connected with the existence of conjugated reaction chains localized in separate zones of polymer chain-sponge micelles. Special attention is paid to the mechanism of the process proceeding during the induction period of polyolefine autoxidation which contain sterically hindered alkylated phenols. The induction period precedent to the stage of direct polymer oxidation is characterized as a stage of chain co-oxidation of an antioxidant and a polymer. This chain stage is the steady state order zero or one reaction by alkylphenol in dependence on its molecular structure.
