Different techniques were used to analyse the reaction mechanisms and kinetics of the system 2,2-[4-(2,3-epoxypropyl)phenyl]propane polycondensed with 4,4′-sulphonyl-dianiline in the temperature range 100?185°C. The results show the role of catalysts, of stoichiometry and of curing cycles in the reaction mechanisms and paths. Based on chemical balances of residual epoxy groups, and of hydroxy and ether groups formed, we have shown the effect of these functions on the thermal properties of the material. |
