摘要: Abstract Studies are reported on the rearrangements which occur in epoxy resins when heated above 497 K. The nature of processes resin and model compounds is discussed with reference to changes ultraviolet, infra-red 13C 1H NMR spectra. Chain scission preceded by dehydration glycidyl segment occurs at CN OC bonds, generating phenoxy radicals latter case. observed coloration high temperatures associated formation a polyenyl structure possible generation quinoid cyclic conjugated nitrogen-containing aromatic ring structures.
