Abstract :
The glass transition temperature Tg of polymers is identified by terahertz time-domain spectroscopy (TDS). The thermo-quasi-optic coefficient noticeably changes in the region of the glass transition. THz TDS can thus serve as a non-destructive and non-contact technique for polymer analysis.
