中文摘要	phenolphthalein poly(ether ether sulphone) (pes-c) was found to be miscible with uncured bisphenol-a-type epoxy resin, i.e. diglycidyl ether of bisphenol a (dgeba), as shown by the existence of a single glass transition temperature within the whole composition range. miscibility between pes-c and dgeba is considered to be due mainly to the entropy contribution. however, dynamic mechanical analysis (d.m.a.) and scanning electron microscopy (sem) studies revealed that pes-c exhibits different miscibility with four cured epoxy resins (er). the overall compatibility and the resulting morphology of the cured blends are dependent on the choice of cure agent. for the blends cured with amines (4,4'-diaminodiphenylmethane (ddm) and 4,4'-diaminodiphenylsulphone (dds)), no phase separation occurs as indicated by either d.m.a. or sem. however, for the blends cured with anhydrides (maleic anhydride (ma) and phthalic anhydride (pa)), both d.m.a. and sem clearly show evidence of phase separation. sem study shows that the two phases interact well in the ma-cured blend while the interface between the phases in the pa-cured blend is poorly bonded. the differences in the overall compatibility and the resulting morphology between the amine-cured and anhydride-cured systems have been discussed from the points of view of both thermodynamics and kinetics.
