FTIR Spectroscopy in Studying the Conformational Transitions of Polyvinylidene Fluoride

Conformational dynamics in polyvinylidene fluoride is studied via IR spectroscopy of conformational probes. The nature of relaxation transitions that occur at temperatures of 180 and 230 K is explained. The possibility of detecting crankshaft-type local molecular motion is demonstrated. The temperatures of transitions, obtained using conformational probes, are compared to those of relaxation transitions discovered by other means of research.
