Abstract :
Isothermal crystallization of poly(3-hydroxybutylate) was observed by the temporal change of terahertz absorption spectra. The obtained spectra were analyzed by using two-dimensional correlation spectroscopy. Synchronous and asynchronous plots show the correlation of the absorption peaks and the order of the spectral change, which helps to understand the crystallization process.
