摘要：
ESR spectroscopy and a nitroxyl radical-probe was used to study the change in segmental mobility of macrochains of high-density polyethylene in the amorphous phase by the action of tensile stress. In the elastic zone of stressing a link was observed between changes of kinetic parameters of the radical-probe and thermodynamic parameters of the polymer sample during deformation. It is shown that in the elastic zone the type of variation of molecular mobility is determined by the degree of orientation of the sample.
