The glass transition temperatures,T g, and thermal effects of polymerization,ΔH, have been determined for five epoxy adhesives of unknown composition. From the trendsΔH vs./t cure it has been possible to attain a phenomenological kinetic order of the polymerization rate at 100° through an iterative calculation procedure. For most of the investigated adhesives there are reasons (double peak of polymerization and doubleT g signal) to assume that they are graft copolymers.
