Abstract (EN): FT-NIR spectroscopy was been describe with a powerful technique to on-line monitoring and control of polymerizations. . In this work this technique was used to monitoring the viscosity of urea-formaldehyde resins during the condensation reaction. The main objective of this study was to develop a chemometric technique that can be used on-line or off-line for determining the resins’ viscosity in the condensation stage. The best model uses the spectral region between 4400-4800 cm-1 and the first derivative with vector normalization for preprocessing.
