Local molecular dynamics in a set of glassy polymers has been studied by the IR-spectroscopic method of conformationally-inhomogeneous probes. This method allows one to determine those macromolecules' fragments, of which ...

© 2019, Allerton Press, Inc. Abstract: The local molecular dynamics in a polymer matrix based on polyvinylbutyral for solid polyelectrolyte is studied by means of FTIR spectroscopy. The effect low molecular weight polyethylene ...

The method of FT-IR spectroscopy of conformational probes was used to study the local molecular mobility of polysulfone and polycarbonate before and after treatment by supercritical carbon dioxide. The temperature and the ...

The IR Fourier transform absorption spectra were used to study the rotational mobility of macromolecule fragments (local dynamics) of several vitreous polyetherimides by the method of conformational probes. The temperatures ...

Infrared absorption spectra and internal rotation of 1,2-di-(p-XC6H4)ethanes (X=Br, NO2) have been investigated. The magnitude of the barrier to internal rotation of 1,2-di-(p-bromophenyl)ethane has been estimated. The ...
