Epoxy resins cured with prepolymers of varying molecular weight were studied by high-resolution pyrolysis-gas chromatography. Various phenols and the glycidylethers of bisphenol A characteristic of the prepolymer backbone were observed in the pyrograms of the prepolymers. In addition, pyrolysates characteristic of the curing agents were also observed in cured resin systems. In both cases, the peak intensities changed as a function of the molecular weight of the original prepolymers. The molecular weights of the original prepolymers were calculated from the peak intensities of the characteristic products for the uncured prepolymers and the cured resins
