摘要： 用4，4′-二氟代二苯甲酰与双酚A的溶液缩聚制得聚醚苯偶酰(PEB)，经邻苯二胺改性后，通过两步法得到聚苯基醚喹噁啉（PEQ-1）。 在PEB的改性反应中加入质量分数分别为1.0%和1.3%的3，3′，4，4′-四胺基二苯醚，可有效增加聚苯基醚喹噁啉的相对分子质量，得到PEQ-2和PEQ-3（总收率≥90%），其质均相对分子质量分别为7.492×104和1.486×105。 并用IR、 NMR等对这些聚合物进行了表征。 该法操作简便，具有潜在的应用价值。

Abstract: Novel poly(aryl ether quinoxaline)s(PEQs) were prepared via a new two-step procedure. First, poly(ether benzil)(PEB) was synthesized by the polycondensation of 4,4′-difluorobenzil and 4,4′-isopropylidenediphenol. Then, PEQ-1 was synthesized through chemical modification of PEB by 1,2-diaminobenzene. The mass average relative molecular mass of the PEQs could be adjusted easily as 7.492×104 and 1.486×105 by the addition of 1.0% and 1.3% mass fraction of 4,4′-oxydibenzene-1,2-diamine, respectively. The total yield of this two-step method is above 90%. The polymers were characterized by IR, NMR and other measurements. The method is simple and has a potential application value.

Key words: poly(aryl ether quinoxaline), poly(ether benzil), synthesis, characterization
