Title: | Investigation of melamine-formaldehyde cure by Fourier-transform Raman-spectroscopy | Authors: | SCHEEPERS, ML KIP, BJ BRANDTS, PM GELAN, Jan ADRIAENSENS, Peter VANDERZANDE, Dirk CARLEER, Robert |
Issue Date: | 1993 | Publisher: | ELSEVIER SCIENCE BV | Source: | VIBRATIONAL SPECTROSCOPY, 6(1). p. 55-69 | Abstract: | Fourier transform (FT) Raman spectroscopy has been used for characterization of melamine-formaldehyde (MF) resins. Band assignments were based on a combination of literature band assignments, a study of the Raman spectra of model compounds and well characterized MF adducts and resins. The triazine ring breathing band at 975 cm-1 and the C-H stretching bands around 3000 cm-1 can be used as internal reference bands in the Raman spectra of MF resins. It is shown that FT-Raman spectroscopy, in combination with C-13 nuclear magnetic resonance and liquid chromatography can bring further elucidation on the methylolation and ether- and methylene-bridge formation in (cured) MF resins. | Notes: | DSM RES & PATENTS,POB 18,6160 MD GELEEN,NETHERLANDS.
