Abstract
The application of infrared spectrometry in the overtone and combination regions (1.0–2.7 μ wavelengths) for determining chemical groups in polymeric materials was studied. Various groups such as CH2, NH, and CO were assigned to spectra of polyethylene, polypropylene, nylon 66, polyisobutylene, polystyrene, polyvinyl acetate, polyvinyl chloride and a polyvinylidene-polyvinyl chloride copolymer. The technique for sample preparation and experimental procedure is given. It is suggested that these spectra assignments in the overtone and combination regions can be used to obtain relative degradation measurements, determine water adsorption, quantitatively measure physical polymer blends, and finally to study polymer reaction kinetics.
