    • The manufacture of polyetherquinoxalines may be accomplished by polymerization of quinoxaline and related monomers with a bisphenol under aromatic nucleophilic substitution reaction conditions. A method of manufacture includes contacting a substituted or unsubstituted quinoxaline having replaceable groups at the 2,3 positions with a bisphenol or a bisphenol derivative under aromatic nucleophilic substitution reaction conditions. The resulting polyetherquinoxalines contain quinoxaline groups joined by ether linkages at the 2 and 3 positions of the quinoxaline groups. In one example, the polyetherquinoxaline has a formula represented as wherein “n” is an integer from 1 to 10000, and R1, R2, R3, R4 are independently hydrogen, methyl, CF3, tert-butyl, benzoyl, benzenesulfonyl, a sulfonic acid salt, an aliphatic group, an alicyclic group, or an aryl group, and Ar is an aromatic radical. These melt-processable polyetherquinoxalines can be prepared under relatively mild conditions, have excellent thermal and mechanical properties, and are organo-soluble, transparent and colorless thermoplastics.
    • 聚醚喹喔啉的制备可以通过在芳族亲核取代反应条件下将双羟基喹喔啉和相关单体聚合而完成。 一种制备方法包括在芳族亲核取代反应条件下使具有2,3位置可替换基团的取代或未取代的喹喔啉与双酚或双酚衍生物接触。 所得聚醚喹喔啉含有在喹喔啉基团的2和3位上通过醚键连接的喹喔啉基团。 在一个实例中,聚醚喹喔啉具有其中“n”为1至10000的整数,R 1,R 2,R 3,R 4独立地为氢,甲基,CF 3,叔丁基,苯甲酰基,苯磺酰基,磺酸 盐,脂族基,脂环基或芳基,Ar为芳香族基。 这些可熔融加工的聚醚喹喔啉可以在相对温和的条件下制备,具有优异的热和机械性能,并且是有机溶性,透明和无色的热塑性塑料。
