Abstract: The FTIR-spectroscopic method of conformational probes combined with the proposed hybrid genetic algorithm was used to study secondary relaxation transitions in polyvinylbutyral in the temperature range of $300\div90$ K. The mobility of the side groups of the macromolecule was characterized. The obtained results was compared with the data from other methods on relaxation transitions at a temperature lower than the glass transition temperature. The influence of supercritical carbon dioxide on the freezing temperature of the conformational mobility of the probe in the polymer was investigated.

Keywords: secondary relaxation transitions, method of conformational probes, genetic algorithm, supercritical carbon dioxide.
