摘　　要：Sulfonated poly（phthalazinone）s （SPPENK, SPPESK and SPPBEK） were prepared by direct polymerization reaction from sulfonated monomers. The novel acid-base membranes were composed of sulfonated polymers as the acidic compounds, and polyetherimide （PEI） as the basic compounds, casting from their N-methylpyrrolidone （NMP） solution directly onto clean glass plates at 60 ℃ aiming at enhancing membrane toughness and other relative properties. The resulted acid-base composite membranes had excellent resistance to swelling, thermo-stability, hydrolysis resistance and oxidative resistance properties with highly ion-exchange capacity （IEC）.Sulfonated poly（phthalazinone）s （SPPENK, SPPESK and SPPBEK） were prepared by direct polymerization reaction from sulfonated monomers.
