THE FREE ROTATION OF SIMPLE MOLECULES

AND CHARACTERISTIC TEMPERATURES IN VITREOUS

POLYMERS

V.A Ryzhov

Ioffe Physical Technical Institute, St. Petersburg

Purely rotary ranges of molecules of NH3 and HCl added as a probe in polypropylene (PP) and polyvinylchloride (PVC) are received and analyzed. It is shown that local dynamics of a polymeric matrix has on a form of strips of these ranges, reflecting extent of indignation of a rotary motion, strong impact. On change of integrated intensity of absorption with a temperature transition temperatures from free rotation of molecules of NH3 and HCl to their libration, and also temperatures of the beginning of defrosting of conformational mobility of chains of macromolecules of PVC and PP are found.

Keywords: PP, PVC, the free rotation of the molecules.
