## Abstract With the aim of improving the performance of conventional proton conducting membranes, systems based on two poly(arylene ether sulfone)s and two elastomers were obtained by heterogeneous sulfonation with chlorosulfonic acid. Subsequently, they were characterized, morphologically and ele

New aromatic copolymers bearing polar pyridine units in the main chain have been synthesized. Depending on the content of the pyridine monomer, soluble, high molecular weight polymers were obtained. The studied copolymers showed high thermal and oxidative stability and high T g values but moderate a

## Abstract Polyphenylsulfone was sulfonated by two different methods: reaction with SO~3~ and reaction with (CH~3~)~3~SiSO~3~Cl. The products were characterized, and the advantages of both methods are discussed. Much more homogeneous products were obtained from the reaction with (CH~3~)~3~SiSO~3~C

By using camphorsulfonic acid (CSA) to protonate polyaniline (PANI), the counterion enabled the PANI-CSA complex processable as a solution phase. So camphorsulfonic acid (CSA)-doped polyaniline/polyimide (PANI/PI) blend films were prepared by the solvent casting method using N-methylpyrrolidinone (N
