The oxygen pressure effect on the oxidation process of strained elastomers provides the experimentally observed complex pressure dependence of the process rate. Originally increasing the oxidation rate is then dropping with the increase of oxygen pressure from 30-730 mm Hg. The similar behaviour of the dependence is explained by the dual role of the pressure in the above process. The relation between the oxidation and the oxygen pressure is presented. The value of activation volume of 2.5 × 104-2.5 × 105 cm3/mol obtained using the above relationship is explained by the activation zone theory. The increase of oxidation rate at P-const and fixed mobility of the molecules, relaxation times and the diffusion coefficient effected by stretching loads is explained by the volume activation dependence of the deformation. The computer simulation of the obtained relation is provided confirming all the experimentally observed pressure features of oxidation of strained and unstrined elastomers. |
