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.
