“…The values of the constants used in these simulations are summarized in Table 2. Also shown are the ranges of parameter values investigated, namely the underlying heating rate, q, the reaction orders, m and n, in Equation (2), the parameter λ of the DiBenedetto equation, Equation (6), and the reduced activation energy, E f /R, in Equation (7 [18] Equation (3) E c1 (kJ mol -1 ) 51.8 [18] Equation (3) A 2 (s -1 ) 10 3.4 [18] Equation (3) E c2 (kJ·mol -1 ) 41.5 [18] Equation (3) k dg (s -1 ) 0.0051 [14] Equation (4) C 1 40.2 [17] Equation (4) C 2 (K) 51.6 [17] Equation (4) T g0 (ºC) -15 Equation (6) T g∞ (ºC) 80 Equation ( …”

“…Equation (3) was found to give satisfactory agreement with experimental data for several epoxy-amine systems but in a rather limited range of conversion (generally up to x ¼ 0.5-0.6). [10][11][12] The deviations observed at high conversions are usually ascribed to the onset of diffusional restrictions. [8,12] Deviations can also arise from side reactions during epoxy cure such as intramolecular or intermolecular etherification and epoxy homopolymerization.…”

“…Apesar de sua simplicidade, descreve satisfatoriamente a cinética desse sistema reacional para situações não-isotérmicas [19][20][21], especialmente quando se utiliza baixas taxas de aquecimento, já para o caso isotérmico, essa aplicabilidade não é um consenso [9;22]. Com relação ao modelo de Kamal, a introdução do ajuste dos parâmetros m e n, ajuste este que introduz uma característica empírica ao modelo, também fornece uma maior flexibilidade ao mesmo [19].…”
