Abstract

Isothermal and non-isothermal kinetic studies of liquid processable multicomponent commercial amine-cured epoxy resin were evaluated. The corresponding viscosity development and phase transition behaviour of this amine-cured epoxy blend were investigated. The rate constants of each combination were calculated highlighting the reaction speed between different components in various reaction processes, indicating the reaction probability between each component. As expected, the epoxy resin cured with highly reactive hardeners shows a higher Tg, presumably due to the formation of a more densely cross-linked network in this blend. However, it is worth noting that incorporating a high reactive hardener did not significantly influence the Tg of the multi-component blend. This was attributed to the participation of IDPA and POP in the following bridge-forming process after the ring-opening process instigated by AEPIP
