The application of Fourier transform Raman spectroscopy to the identification and characterization of polyamides—I. Single number nylons
Abstract
High quality Fourier transform Raman spectra, free from fluorescence, have been obtained for a series of commercial polyamides of the single number nylon type from nylon 3 to nylon 12. With this newly developed technique, it is now possible to record spectra routinely and to characterize each nylon spectrum thus to identify them for analytical purposes. The characteristic trends observed in some regions of the Fourier transform Raman spectra obtained for this series of nylons are investigated and discussed.
