Abstract: Different polyetherimides of varied chemical structure were synthesized to toughen tetraglycidyl-4,4′-diaminodiphenylmethane(TGDDM) epoxy resin. The effects of miscibility and viscosity of polyetherimide on the phase separation and morphological evolution during the cure reaction of the toughened system were characterized by using DSC, time-resolved light scattering(TRLS) and SEM. Both thermodynamic and dynamic factors were emphasized to control the morphology of cure reaction induced phase separation system.

Key words: Polyetherimide, TGDDM epoxy resin, Phase separation, Thermodynamics, Kinetics
