PMMA based proton conducting Polymer electrolytes with Pure PMMA and 80 PMMA: 20 C₆H₁₀O₄ have been prepared by Solution Casting Technique using DMF as solvent. FTIR studies reveal the complex formation between the salt and polymer matrix. Conductance spectra analysis reveals that the incorporation of salt Adipic acid to Pure PMMA dc conductivity value of Pure PMMA increases from 5.5758X10^-7 Scm^-1 to 1.5233X10^-6 at ambient temperature. Admittance analysis is the double check for the conductivity obtained from conductance analysis. Magnitude Bode ploy shows the decline in the impedance with the addition of adipic acid to pure PMMA.
