Link between the activation parameters of deformation of network polymers in the transitional region and the properties of the glassy state

Abstract It is shown that the activation parameters of deformation in the transitional region reflect the structural features and properties of glassy epoxide polymers. An analogy is drawn between thermal and deformation softening. The temperature intervals determining the different patterns and mechanisms of strain have been found. The structural factors of the network polymer determining the signs of plastic strain characteristic of crystalline bodies have been identified.
