Annotation
Fluorescence spectroscopy with the application of fluorescent molecular probes is used to determine the temperature ranges in which vitrification of the surface layer of polystyrene with different molecular masses typically occurs. It is found that the surface vitrification temperature is significantly lower than the bulk values. The results of the study are in good agreement with the data obtained earlier using an independent technique.
