Synthesis and Characterization of Novel Sulfonated Poly( Arylene Ether Sulfone) Containing Fluorine Group


Article Preview

A series of novel sulfonated poly(arylene ether sulfone) (SPAES) were prepared by aromatic nucleophilic substitution polycondensation of 4,4’-dichlorodiphenylsulfone (DCDPS), 3,3’-disulfonated-4,4’-dichlorodiphenylsulfone (SDCDPS) and new type fluorinated bisphenol monomer---4-fluorophenyl hydroquinone. Different degree of sulfonation (DS) of these SPAES could be controlled by varying the feed ratio of SDCDPS to DCDPS. High molecular weights of the products were confirmed by inherent viscosity, which could reach 2.43 dl/g. The structures of the obtained polymers were characterized by FTIR, NMR. DSC and TGA analyses explained the excellent thermal properties of the resulting SPAESs. The temperatures at 10% weight loss were higher than 513°C. Furthermore, all the polymers showed excellent solubility in common organic solvents, such as NMP, DMAC, and DMF. So the films of SPAESs could be casted from their solutions.
