Dihydro-4-(4-hydroxyphenyl)(2H)phthalazin-1-one(DHPZ) was sulfonated in con- centrated sulfuric acid. Poly(phthalazinone ether ketone) containing pendant sodium sulfonate group was synthesized from sulfonated and pure 1,2-dihydro-4-(4-hydroxyphenyl)(2H)phthalazin- 1-one, and 4,4-difluorodiphenylketone. The sulfonated monomer and sulfonated polymer were characterized with FT-IR and 1H-NMR.
Poly (phthalazinone ether ketone) containing pendant sodium sulfonate group was synthesized from sulfonated and pure 1,2-dihydroxy-4- (4-hydroxyphenyl) (2H) phthalazin- dihydro-4- (4-hydroxyphenyl) (2H) phthalazin-1-one, and 4,4-difluorodiphenylketone. The sulfonated monomer and sulfonated polymer were characterized with FT-IR and 1H-NMR.
