The ultrafiltration membrane was prepared from an aromatic polyamide containing 1,2-dihydro-4-phenyl(2H)phthalazinone moiety it is soluble in DMAc, DMF, NMP, DMSO and m-cresol. The effects of solvents, polymer concentration, additive, and temperature of gel bath on the membrane performance were studied. While DMAc was used as solvent and ethylene glycol methylether or diethyl ether was used as additive, the rejection against PEG12000 was up to 100% under 0.1 MPa.
