AB - An anisotropic copolymer film of vinyl chloride and vinyl acetate, which has shape memory properties, was investigated by the molecular probe method, thermomechanical analysis, and scanning calorimetry. It was found that the amorphous‐crystalline structure and the stress–strain state of the surface layer of the film differ from the structure and state of the inner layers. The molecular probe (limited diffusion of a solvent into the surface layer of the film) revealed the localization of the elastic deformation energy of a film, which was rapidly cooled in a stressed state during production. It is shown that destroying/crushing the stressed macrostructure of the film surface via plasticization and dissolution of the copolymer, eliminates the effects of the elastic energy release during thermally stimulated shrinkage.
