Abstract
This work reports the synthesis and electrical characterization of sulfonated copolymer with flexible carboxylic acid pendants with 1,3,4-oxadiazole unit in the main polymer structure contrived successfully via nucleophilic displacement polycondensation among 2,5-Bis(4-fluorophenyl)-1,3,4-oxadiazole (BFPOx), 4,4′-Bis(4-hydroxyphenyl) valeric acid (BPV) and Disodium-3,3′-disulfonate-4,4′-dichlorodiphenylsulfone (S-DCDPS). The molecular structural characterization of the copolymer was achieved by NMR spectroscopic studies, TGA was performed to verify the thermal stability, dielectric studies were executed by compressing the copolymer sample in to tablets and results were discussed.
