ABSTRACT The curing processes of epoxy resins cured with a dicarboxylic acid anhydride or in the presence of an imidazole catalyst were studied by high-resolution pyrolysis-gas

chromatography. The yields of the pyrolyzates with epoxide groups decreased with increase in the degree of curing, while those of various phenols characteristic of prepolymer skeleton

increased. Additionally, the yields of low boiling pyrolyzates such as ethylene oxide, propylene, acrolein and acetone also specifically changed with the degree of curing. The obtained

results are discussed in comparison with the results from other techniques such as glass transition temperature measurements and FT-IR. SIMILAR CONTENT BEING VIEWED BY OTHERS INVESTIGATION
