以聚酞嗪酮（PPEK）为原料，在98%的浓硫酸和三甲胺中与氯甲基甲醚进行氯甲基化和季铵化反应，合成了季铵化聚酞嗪酮（PPEK）。通过1H-NMR证实了氯甲基化PPEK中存在CH2Cl基团。制备了碱性QPPEK膜，并对其热性能和力学性能进行了测试。碱性QPPEK膜的甲醇渗透率为6.57 × 10−7 cm2/s，阴离子电导率最高为1.14 × 10−2 s /cm。©2008 Wiley期刊公司高分子学报，2008
Quaternized poly(phthalazinone ether ketone)s (QPPEK)s were synthesized by the chloromethylation and quaternization of poly(phthalazinone ether ketone) (PPEK) with chloromethyl methyl ether in 98% concentrated sulfuric acid and following trimethylamine. The presence of CH2Cl groups in chloromethylated PPEK was confirmed by 1H-NMR. An alkaline QPPEK membrane was prepared and its thermal and mechanical properties were tested. The alkaline QPPEK membrane had a methanol permeability 6.57 × 10−7 cm2/s and the highest anion conductivity 1.14 × 10−2 S/cm. © 2008 Wiley Periodicals, Inc. J Appl Polym Sci, 2008
