Abstract
In this study, near-infrared transmission spectroscopy is investigated as an alternative technique for the real-time cure monitoring of thermosets systems. Two polymer systems based on dimethacrylate/styrene and dimethacrylate/divinylbenzene monomers were studied in order to check the influence of comonomer functionality. A new device utilizing ITO (indium-tin-oxide)-coated glass plates was developed to take into account the specificity of chain polymerization: oxygen inhibition, bulk polymerization, etc. Two absorption bands at 6166 and 6135 cm-1 suitable for
