Resumo

An analysis of local mobility of macromolecule of polyvinylpyrrolidone is carried out by use of IR spectroscopy. The freezing temperature of local molecular mobility is determined and the type of relaxator is established. The secondary relaxation transition of polyvinylpyrrolidone is detected at the temperature of 235 K.
