Characterization of Synthetic Rubber using FTIR Spectroscopy

One of the most characteristic amorphous bands of PLLA at 1265 cm , which was assigned to coupling of the C—O—C stretching and C—H deformation modes was also missing from the spectra of the 20/80 PHB-co-HHx/PLLA blend. Thus, the spectra of the 20/80 PHB-co-HHx/PLLA blend were very similar to the neat crystalline PLLA spectra. Infrared microspectroscopy revealed that PHB and PHB-co-HHx, but not PLLA, were crystallized in the 80/20 blends. These results also indicated that the PHB-co-HHx component, when dispersed in a PLLA matrix at a relatively low level, did not undergo significant crystallization. 

Characterization of Synthetic Rubber using FTIR Spectroscopy 

Bandyopadhyay et al. 108] used infrared spectroscopy to identify the polymer, the polymenblend ratio calculation, the raw material evaluation, the study of reaction mechanism, and the microstructural determination. When NR was characterized using FTIR, the absorbance ratio of specific peaks of different grades of
