T he kinetics of cracks growth in synthetic isoprene rubber (SIR-3) vulcanizates in the atmosphere of ozone was studied by the method of optical microscopy. The average value of cracks surface was used as a measure of the degree of cracking. The growth of surface cracks involves two stages: a relatively slow in the beginning and faster, which is flowing at a constant rate. An empirical relationships that describe this process at different concentrations of ozone were proposed. A physical interpretation of the constants appearing in the empirical relationships was given.
