Abstract :
Isothermal crystallization of poly(3-hydroxy-butyrate) was studied by terahertz time-domain spectroscopy. The temporal change of the ratio between the crystalline and amorphous structure was estimated by the integrated absorption intensity. The crystallization process was discussed by using Avrmi´s equation.
