    abstract = {Composites materials are used in many applications: Solar 
  cells, Light Emitting Diodes (LED), optoelectronic device, industrial applications 
  in aircraft, military and car industry for their low cost, light weight, electrical 
  properties, mechanical and optical properties. 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.}
