Abstract
Near- and mid- infrared spectroscopy techniques were used to study the cure reaction of accelerated diphenyldimethylurea (Diuron) epoxy form ulation based on diglycidyl ether of bisphenol A (DGEBA) prepolymer cu ring with dicyandiamide (DDA) hardener. This study was carried out usi ng a classic Fourier transform infrared spectrometer generally availab le in many laboratories, and it revealed the possibilities and problem s that occurred in quantitative analysis. Thus, new assignments in NIR range and light scattering influence for this heterogeneous system ar e studied. Molar absorption change and comparison of the epoxy convers ion determined by NIR spectroscopy (4530 cm(-1) epoxy band), MIR spect roscopy (915 cm(-1) epoxy band), SEC, and chemical titration are then successively presented and discussed.
