Notizen: Laser Raman spectroscopy was used to analyze the structures of urea-formaldehyde resins. Band assignments were made on the basis of Raman studies of model compounds. Methylol and certain methylene functionalities could be differentiated in both the model compounds and the resins. Spectra of the resins at various stages of cure were also examined. Trends noted agreed with earlier studies on the kinetics and the proposed mechanism of the cure process. Laser Raman spectroscopy offers promise for elucidating the structures of urea-formaldehyde resins and for providing insight into the molecular phenomena of the cure and degradation of these resins.
