摘　　要：通过亲核缩聚反应由酚酞、4,4′-二氟二苯酮和2,6′-二氯苯腈制备了一系列不同腈基含量的无定型聚芳醚腈酮共聚物。通过FT-IR、1 H-NMR、13 C-NMR、DSC、TGA等表征了聚合物的结构与性能。研究表明:随着腈基含量的提高,聚合物的玻璃化转变温度升高,在马口铁板上的附着力逐渐提高;该聚合物在有机溶剂中具有良好的可溶性和成膜性,聚合物涂层具有优异的综合性能。A series of amorphous poly（aryl ether nitrile ketone） copolymer with different percentages of cyano were synthesized by nucleophilic polycondensation from phenolphthalein, 2,6′-dichlorobenzonitrile and 4,4′-difluorobenzophenone. The structure and properties of copolymer were characterized by FT- IR, 1H-NMR, 13C-NMR, DSC, TGA etc. With the increasing of cyano concentration in copolymer structure, the glass transition temperature and adhesion strength to the tin plate increased gradually. Results show that the copolymer has good solubility in organic solvents, which results in good ability of film forming. The coating layer has excellent overall performance.
