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
