- 摘要： A series of novel poly(aryl ether nitrile)s containing phthalazinone moiety were synthesized by the nucleophilic displacement reaction of bisphenol-like monomers (1) 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 degrees C, and the temperatures for 10% weight loss in nitrogen atmosphere were found between 495 and 527 C. The structures of these resultant polymers were confirmed by FT-IR and H-1 NMR. Moreover, the properties of poly(aryl ether nitrile)s including solubility and crystallinity were also studied.
