 In this study, poly(styrene-co-vinyl benzyl trimethyl ammonium chloride) with different styrene to vinyl benzyl chloride ratio (3:1, 1:1, 1:2) have been synthesized. The formation ofproducts was confirmed by Fourier transform infrared spectrophotometry (FTIR) and nuclear magnetic resonance spectra (1H NMR). Then, anion exchange membranes were prepared by combination of poly(styrene-co-vinyl benzyl trimethyl ammonium hydroxide) and poly (vinyl alcohol) The obtained membranes were evaluated for their own conductivity, anion exchange capacity, and thermal decomposition. The results showed that the anion exchange membrane produced from copolymer with styrene to vinyl benzyl chloride ratio 1: 2 exhibited good hydroxide conductivity of 7 mS/cm, ion exchange capacity was 0.65mmol/g and stability to 200oC.
