o-and p-Hydroxymethyl phenyl glycidyl ethers were synthesized as model compounds of hydroxymethyl diglycidyl ether bisphenol A type epoxy resin. It was reported to give more rapid cures at lower temperatures with amines for having a hydroxymethyl activating group. The reactions of these compounds with methylene dianilineniline-(MDA) were investigated by means of DTA and IE for the discussion of "anchimeric effect" suggested by Schwarzer.
