Identification of monomers with Raman spectroscopy

Polymers are comprised of macromolecules that are in turn comprised of numerous identical or similar structural units that are referred to as monomers. This Application Note shows the convenient identification of conventional monomers within seconds using the portable Mira M-1 spectrometer. Monomers such as styrol, various alkyl methacrylates, divinylbenzene, ethylene glycol, phenol, terephthalic acid and urea have been investigated. Additives or inhibitors such as benzoquinone can be identified quickly and unambiguously.
