Interfacial kinetics of a model epoxy-amine addition reaction.

The kinetics of the addition reaction at a solid interface for a model epoxy-amine system composed of monofunctionalized phenyl glycidyl ether and hexylamine was examined. The chemical character for the reaction of this system at the interface was the same as that in the bulk, while the physical nature was significantly different. Slowing down of the diffusion for the reactants in close proximity to the solid interface was also addressed by interfacial selective spectroscopy.
