Analysis of the Local Mobility of the Polyvinylpyrrolidone Macromolecule
摘要
Abstract
The local mobility of the polyvinylpyrrolidone macromolecule was analyzed by IR spectroscopy. The freezing temperature of local molecular mobility was found, and the type of the relaxator was determined. A secondary relaxation transition of polyvinylpyrrolidone was detected at a temperature of 235 K.
