Aromatic sulfone ether diamine, bis[4-(4-aminophenoxy)phenyl]sulfone (SED), was prepared by the nucleophilic aromatic substitution of 44'dichlorodiphenylsulphone by p-aminophenolate. The reaction was conducted in the presence of excess potassium carbonate as a weak base, toluene as the dehydrating a

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 The poly(sily ether) with pendant chloromethyl groups (PSE) was synthesized by the polyaddition of dichloromethylsilane (DCM) and diglycidylether of bisphenol A (DGEBA) with tetrabutylammonium chloride (TBAC) as a catalyst. This polymer was miscible with diglycidyl ether of bisphenol A
