Abstract
Methods are given for the‘derivatisation’ of various of the components of epoxy resins: after fractionation by g.p.c. but before further analysis by h.p.l.c. or g.p.c. This paper describes the use of the following reagents for this purpose: concentrated HCl (to convert epoxy groups into chlorohydrin units); solid NaOH (to convert 1, 2-chlorohydrin groups into epoxy units); phenol (to open epoxy rings); N-methylaniline (to open epoxy rings); and KMnO4 (to oxidise —CH2 — and — OCH2CHOHCH2O — bridging units).
