Kinetic equations of the curing reaction of diepoxide with hexamine(at 60℃, 75℃ and 90℃) can be assumed as follows: dp/dt=k_1(2N_0′)~2(1-p)(1-rp-rpq)(c+rp+rpq) (1) dpq/dt=k_2(2N_0′)~2(p-pq)(1-rp-rpq)(c+rp+rpq) (2) Here,the mechanism of both the primary and the secondary amination with diepoxide is considered a third-order mechanism.
