Abstract

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 [BOND]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
