dc.description.abstractSUMMARY SYNTHESIS AND CHARECTERIZATION OF CONDUCTING GRAFT COPOLYMERS BASED ON OLIGOPHENOL ARIKAN, Ufok Niğde University Graduate School of Natural and Applied Sciences j-^v-i^tu unun ui v^u^jiiibli y Graft copolymer of oligo-2-aminophenol(OAF) with thiophene side groups and polypyrrole were synthesized by electrochemical polymerization methods. OAF was synthesized from the use of oxidative polycondensation of 2-aminophenoI with hidrogen peroxide in an aqueous alkaline medium between S0-82°C. OAF was characterized by JH- NMR and FT/IR spektrometers. The number average moleculer weight, weight average moleculer weight and poiydispersity index values of OAF were found to be 307, 308 and 1.005 respectively. Oligo-2-aminophenoI with thiophene side groups(TOAF) were obtained from the reaction between OAF and thiophene-3 -acetic acid. TOAF was charecterized by 'H-NMR and FT/IR. The number average moleculer weight, weight average moleculer weight and poiydispersity index values of TOAF were foud to be 539, 630 and 1.17 respectively. The syntheses of copolymer oügo-2-aminopheno! with thiophene side groups and polypyrrole was achieved electrochemically by using three different supporting electrolytes; p-toluen sulfonicacid{PTSA)water, sodium dodecyl sulfate(SDS)/water, tetrabutyl amonium tetraflouro borate(TBAFB)/acetonitrile. Characterization of oligo-2-aminophenoI with thiophene side groups and polypyrrole was carried out by combination of techniques including scanning electron rnieroseopy(SEM), thermal gravimetry(TGA), differential scanning eaiorimetry(DSC), H-NMR and FT/IR methods. Electrical conductivity measurements were carried out by using the standart four-probe tecnique. Conductivities of the copolymer doped with PTSA were measured as 4.1-4.5 S/cm.
