Abstract : Stretching as a method of physical modification of the properties of polymers basic on the creation of primary orientation of the macromolecules in polymer material is a widely used technique, but the phenomena which take place during the orientation, particularly the processes of restructing the supermolecular structure, especially in amorphous polymers have remained outside the field of view of researchers. In only one of the works of Zhurkov and his associates were there presented data concerning changes in the supermolecular structure of PMMA polymethylmethacrylate, but even in this work there was electron microscopic study of only the non oriented polymer which had been stretched to its limits under test.
