In this paper we have studied the conformational dynamics of conformationally-heterogeneous probes in the blends of polyvinyl butyral (PVB) and polyethylene glycol (PEG600) with molecular weight equaled to 600. We have determined the freezing temperatures of conformational transitions and the enthalpy differences of conformations of the probes in PVB/PEG600 blends with different compositions by FTIR spectra.
