| Abstract: | FTIR in situ was used to study the isothermal reaction kinetics of o-cresol novolacresin using phenol novolac acetate as the curing agent in the presence of 2-methylimidazole.Some kinetic parameters of the curing reaction were obtained. The results show that thiscuring process followed a first-order kinetics. The possible mechanism of cured reaction wasdiscussed according to variation in absorption bands of C=O during the reaction. |
