An approach to the analysis of crosslinked epoxy systems

Summary The most widely use epoxy resins are the diglycidylethers of bisphenol A which in both the uncured and curd states posses functional groups that are theoretically amenable to cleavage using the vigorous conditions possible with acid or alkaline fusion chromatography.The cleavage of the simple oligomeric epoxy resins has been investigated together with their crosslinked products with diprimary amines of increasing molecular weight, several polyamines and dimer fatty polyamides. The results are discussed with regard to other polymer systems incorporating bisphenol A.Dedicated to Professor Leslie S. Ettre on the occasion of his 70th birthday.
