Abstract

Department of Physical Chemistry, School of Chemistry, Madurai Kamaraj University, Madurai, IndiaReceived September 14, 2011, Accepted September 21, 2011High molecular weight tetrasulfonated poly(arylene biphenylsulfone ether) (TsPBPSEH) copolymers contain-ing up to four pendant sulfonate groups per repeat unit were synthesized via aromatic nucleophilic displacementcondensation from 4,4'-bis(4-chloro-3-sulfonatophenylsulfonyl)biphenyl-2,2'-disulfonate (SBCSBPD), 4,4'-dichlorodiphenylsulfone (DCDPS) and 4,4'-(hexafluoroisopropylidene)diphenol (6F-BPA). The synthesizedcopolymers were structurally characterized using
