Popis: | Raman spectroscopy was used to monitor the curing process of a benzoxazine monomer. The reaction follows an autocatalytic mechanism. The autocatalytic model described in Kamal equation was employed. The activation energy and the pre-exponential factor were determined as: Ea = 60.52 kJ mol−1 and A = 6.09 × 105 min−1. The overall reaction order was found to be 1.731 ( n = 1.078; m = 0.653). The kinetic model characterized by these values is in good agreement with the experimental values. |
