Most kinetic studies of epoxy-amine systems have focused on the rate of reaction between epoxy and amino groups. The etherification reaction, which occurs at higher temperature and later stages of cure, has been addressed by few investigators. An expression for the rate of etherification in a model compound system, composed of phenyl glycidyl ether(1,2-epoxy-3-phenoxypropane) and aniline is presented in this paper.
