The main goal of the paper was to investigate the influence of severe torsion deformation on the polymer structure and physics properties. Quasihydrostatic pressure up to 6 GPa and torsion deformation into interval 0,1<a<1 were used. The poly(methylmetacrylate)s (1), poly(ethylene)s (2), and poly(thtalydilidenebiphenilylene)s (3) were used . Polymer films were used in the experiments. Film thicknesses were in the range from 100 mkm to 300 mkm with a diameter ~ 10 mm. Structural properties of the samples controlled by X-ray diffraction and polarizing-optical microscopy. And physics properties controlled by measurement following parameters: permittivity, conductivity, electronic paramagnetic resonance, thermogravymetry and others. Some stages of structural transformations, chemical structure changing and appearing new physics properties of the polymers were discovered.
