A random copolymer poly-methyl methacrylate-1-vinyl-3-butylimidazolium bromide[P(MMA-VBIMBr)]was synthesized via radical solution copolymerization with methyl methacrylate(MMA)and 1-vinyl-3-butylimidazolium bromide(VBIMBr)as monomers,and the polymer electrolytes comprising a blend of the corresponding copolymer P(MMA-VBIMBr)as a host polymer and BMIMBF4 as plasticizer were prepared by solution casting technique. Performances of the synthesized copolymer and prepared pol-ymer membrane and electrolyte were studied by FTIR,XRD,SEM,TG and EIS. The result showed that the polymer electrolytes possess excellent thermal stability and fine mechanical performance;and ionic con-ductivity value reached up to 2. 77 × 10 - 3 S / cm with BMIMBF4 / P(MMA-VBIMBr)mass ratio of 2:1 at 20 ℃. The temperature dependence of the polymer electrolyte complexes appeared to obey Arrhenius equation.
