Poly(ether sulfone) and poly(ether sulfone ketone) copolymers (I-V) were synthesized by the nucleophilic substitution reaction of 4,4Ј-dihydroxy diphenyl sulfone (DHDPS, A) with various mole proportions 4,4Ј-difluoro benzophenone (DFBP, B) and 4,4Ј-difluoro diphenyl sulfone (DFDPS, C) using sulfolan
## Abstract A novel class of crosslinkable poly(phthalazinone ether ketone)s with relative high molecular‐weight and good solubility were successfully synthesized by the copolymerization of bisphthalazinone containing monomer, 3,3′‐diallyl‐4,4′‐dihydroxybiphenyl and 4,4′‐di‐ fluorobenzophenone. The
Modification of poly(phthalazinone ether sulfone ketone) (PPESK) by sulfonation with concentrated or fuming sulfuric acid as sulfonation agents was carried out to prepare membrane materials with increased hydrophilicity and potentially increased fouling resistance. Sulfonated PPESK (SPPESK) copolyme
