Abstract: | Conclusions 1. It has been experimentally established that the deformation of crystalline polymers is accompanied by the shear transitions between lamellar crystals of different orientations characteristic of martensitic structures.2. It is concluded that the reversibility of the large deformations of linear polymers is martensitic in nature.For communication 1 see 1].E. O.
