The effect of the amount of curing agent on phenyl-terminated polyetherimide modified TGDDM systems has been studied by using DSC, time resolution light scattering (TRLS) and SEM, Increase of the amount of curing agent will enhance the rates of curing reaction and phase separation, thus change apparently the phase structure of TGDDM/P-PEI (20 phr) blends and the shearing strength. An autocatalytic mechanism was observed for both neat epoxy and the epoxy/PEI blends, but the reaction rates for the blends were higher than that of the neat epoxy due to the presence of PEI.
