Abstract
This paper deals with the radiochemical titration of carbon fibres (ex -PAN AS4 from Hercules) with C-14 labelled succinic anhydride in view of quantifying the reactivity between anhydride groups and the functio nalities (amine, hydroxyl, etc.) of C fibres. A transesterification re action due to the chemical labelling procedure is observed and is conf irmed by time-of-flight secondary ion mass spectrometry (ToF-SIMS) ana lyses. It is finally used for discriminating between the reactivity of anhydride towards amino groups and other fibre functionalities. (C) 1 998 Elsevier Science Ltd. All rights reserved.
