synopsisThe application of infrared spectrometry in the overtone and combination regions (1.0-2.7 p wavelengths) for determining chemical groups in polymeric materials was studied. Various groups such as C&, NH, and C=O 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.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
