A series of novel poly (aryl ether nitrile) s containing phthalazinone moiety were synthesized by the nucleophilic displacement reaction of bisphenol-like monomers (Ⅰ) with 2, 6-difluorobenzonitrile. The inherent viscosities ranged from 0.46 to 1.07 dL g^-1.The glass transition temperatures were in the range of 277-295℃, and the temperatures for 10% weight loss in nitrogen atmosphere were found between 495 and 527℃. The structures of these resultant polymers were confirmed by FT-IR and ¹H NMR. Moreover, the properties of poly (aryl ether nitrile) s including solubility and crystallinity were also studied.
