Synthesis and Characterization of Poly(phthalazinone ehter sulfone ketone)s Containing Sodium Sulfonate Groups

Abstract

Abstract: 4, 4'-Dichlorodiphenylsulfone(DCDPS) was sulfonated in fuming sulfuric acid. Poly(phthalazinone ether sulfone ketone)s were synthesized from 4-(4-hydroxyphenyl)-1-phthalazinone(DHPZ), 4,4'-dichlorodiphenylsulfone, sulfonated 4,4'-dichlorodiphenylsulfone(SDCDPS) and 4,4'-diflorodiphenylketone(DFDPK) in the presence of potassium carbonate in sulfolane. High molecular weight polymers with different degrees of sulfonation were obtained with intrinsic viscosities between 0.86 and 1.21 dL/g. The structure of sulfonated 4,4-dichlorodiphenylsulfone was confirmed by FTIR and ¹H NMR. Polymers containing sodium sulfonate groups were characterized with IR and 1H NMR. The solubilities of the polymers were studied.

Key words: Sulfonation, Poly(phthalazinone ether sulfone ketone), Polymerization
