Abstract: We investigated the effect of lithium trifluoromethanesulfonate (LiCF_3SO_3) on the optical properties of poly(methyl methacrylate) (PMMA), known as a glassy transparent polymer. The absolute values of the stress-optical coefficients in both the glassy and rubbery states were found to be reduced by the addition of LiCF_3SO_3. Furthermore, the linear coefficient of thermal expansion of the blend containing 10 wt.% of LiCF_3SO_3 was lower than that of pure PMMA, suggesting that the birefringence caused by thermal expansion in laminated display systems would be greatly reduced. These results indicate that PMMA/LiCF3SO3 is an appropriate blend for optical films used for liquid crystal displays.
