The physical aging process of 4,4 -diaminodiphenylsulfone (DDS) cured diglycidyl ether bisphenol-A (DGEBA) blended with poly(ether sulfone) (PES) was studied by differential scanning calorimetry (DSC) at four aging temperatures between T g -50ΠC and T g -10ΠC. At aging temperatures between T g -50 a
## Abstract One of the useful methods to improve the toughness of epoxy resin is by mixing the resin with poly(etherβsulfone) (PES). In the present work, two hydroxylβterminated PESs with molecular weights __M__~n~ = 28 600 and 4 200 were used for blending with epoxy resin. The curing reaction of d
