## Abstract The effects of heat treatment on the properties of membranes prepared from blends of poly(ether sulfone)/sulfonated poly(phenylene sulfide) (SPPS) and phenolphthalein poly(ether ether ketone)/SPPS were studied in detail. The membranes' fundamental properties, including water content, tr
Poly(pheny1ene sulfide)-poly(ether sulfone) (PPS-PES) block copolymers were synthesized by polycondensation of chloro-terminated PPS oligomers and hydroxylic-terminated PES oligomers at atmospheric pressure. The structure and compositions of PPS-PES block copolymers were analyzed quantitatively by F
Crystallization and melting behaviors of poly(p-phenylene sulfide) (PPS) in blends with poly(ether sulfone) (PES) prepared by melt-mixing were investigated by differential scanning calorimetry (DSC). The blends showed two glass transition temperatures corresponding to PPS-and PES-rich phases, which
