使用4，4-二氟代二苯甲酰与双酚A的溶液缩聚得聚醚苯偶酰(PEB)，再用邻苯二胺及少量4,4-二苯醚-1,2 二胺（OBDA）对PEB改性，两步法合成得到3种新型聚苯基醚喹噁啉（PEQs）.实验表明这些PEQs聚合物能在多种常规有机溶剂中溶解（如DMF、THF等）；采用四氢呋喃溶解PEQs，将其涂布成膜，发现该膜在可见光区具有良好的透光性（450 nm处的透光率高达85%）；此外，它们还具有较高的玻璃化转变温度（Tg210 ℃）、良好的热性能、优异的耐酸碱性和较好的力学性能，具有潜在应用前景.
Novel poly(aryl ether quinoxaline)s (PEQs) were prepared via a new two-step procedure. Firstly, poly (ether benzil) (PEB) was synthesized by the polycondensation of 4,4-difluorobenzil and 4,4-isopropylidenediphenol. Then, PEQs were synthesized through chemical modification of PEB by 1,2-diaminobenzene and a small amount of 4,4-oxydibenzene-1,2-diamine(OBDA). The polymers were characterized by IR, NMR, TMA and other measurements. Experiments show that these PEQs can be dissolved in common organic solvents, such as DMF and THF; these PEQs were dissolved in THF to get films which had good transmittance in the visible region (the transmittance was up to 85% at 450 nm). In addition, they also had higher glass transition temperatures (Tg210 ℃), good thermal and mechanical properties, as well as excellent resistance to strong acid and alkali. They are expected to be useful functional materials.
