제목 Effect of Difference in Chemical Structure on Reaction Kinetics of Epoxy Resins
초록 Epoxy resins are composed of a three-dimensional network formed by curing reactions between epoxy and amine compounds. Bisphenol-based epoxy compounds, diglycidyl ether of bisphenol A or F (DGEBA or DGEBF), are commonly used. The difference between the two is whether or not two methyl groups are attached to the central carbon of each molecule. However, since the two methyl groups affect the flexibility of rotation, it is expected that their diffusion behaviors will differ from each other. We here examined the reaction kinetics of DGEBA and DGEBF with 4,4’-Diaminophenylmethane as a curing agent. Differential scanning calorimetric measurements revealed that the reaction was slower for the DGEBF system than for the DGEBA one. Discussion on a possible reason for it will be given in our presentation.
