摘要: In this paper, general principles of physical kinetics are used for the description creep, relaxation stress and Young's modulus, fracture a special group polymers. The rates change mechanical properties as function temperature time, stressed or strained highly oriented polymers, is described by Arrhenius type equations. above-mentioned processes found to be determined probability formation excited chemical bonds in macromolecules. statistics certain modes fundamental vibrations macromolecules influence their decisively. If quantum taken into account, an equation adequately describes changes deformation over wide range. Relaxation transitions polymers studied explained substitution classical vibrations.
