The data on strain-induced softening of glassy and The data on strain-induced softening of glassy and crystalline polymers accompanied by development of the crystalline polymers accompanied by development of the capability of high reversible strains in the samples are capability of high reversible strains in the samples are analyzed. It is shown that in the first strain cycle, the test analyzed. It is shown that in the first strain cycle, the test sample demonstrates properties typical of

It is noted that this is capable of high reversible strains. It is noted that this transition represents a physical basis of strain-induced soft-transition represents a physical basis of strain-induced softening of glassy and crystalline polymers.
