In this research, preparation of PS-PMMA copolymer have been investigated. The sodium fluoride was add to PS-PMMA copolymer with concentrations are 0-3 wt.%. The samples were prepared casting technique. The optical properties of composites was measured in the range of the wavelength 200-800 nm. The results showed that the absorption coefficient, extinction coefficient, refractive index real and imaginary dielectric constants of PS-PMMA copolymer are increasing with increase the sodium fluoride concentration.
