In this study, poly(methyl 2- methylpropenoate) (PMMA)- 50 % epoxidized natural rubber (ENR 50) -ammonium thiocyanate (NRISCN) polymer electrolytes were successfully prepared using solution casting technique. The maximum ionic conductivity of 2.51 × 10-8 Scm-1 was achieved for sample with 12 wt.% NH4SCN at room temperature. From Fourier Transform Infrared Spectroscopy (FTIR) analyses it was observed the shifting of the C=O, C-OC and C-O stretching bands in PMMA/ENR 50- NH4SCN polymer electrolyte films. The force constant values for selected bands with various composition of salts was determined and correlated with ionic conductivity.
