Abstract
The results of using the calorimetric method to the mechanism of epoxy-amine cure reaction are presented. Under isothermal conditions, the cure kinetics was analysed by the Mangelsdorf approach. The kinetics of epoxy-amine cure reaction has clearly shown that interaction between epoxy and amine-groups follow the second-order rate law. This finding is important evidence in favour of conception of structured reactive medium during epoxy-amine cure reaction.
It is found that amine excess over epoxide reveals the clear catalytic action. Possible mechanism involving the complex formation between initial reagents is considered.
