Abstract The cure of tetraglycidyl-4,4′-diaminodiphenylmethane with 27 wt% diaminodiphenylsulphone at 160°C was studied using near i.r. spectroscopy. The changes in concentrations of epoxy, hydroxyl, ether and primary, secondary and tertiary amine groups during cure were calculated and empirical reaction rate curves derived for the various functional groups involved. An autocatalytic reaction mechanism was observed for both the primary and the secondary amine group reaction with epoxide. The secondary amine-epoxy reaction showed a substitution effect and is affected by the changes in rheological properties of the resin during gelation and vitrification. Two separate epoxy-hydroxyl reactions are observed, as well as a cyclization reaction due to impurities.
