Haze and transmittance were two important guide lines characterizing the properties of light scattering materials(LSMs). Compound LSMs with PS as light scattering agent and PMMA as matrix were studied.The results showed that LSMs was obtained with only a little PS dispersed in PMMA. The transmittance of LSMs was 80% on condition that the content of PS was 1%; The haze was could be improved from 50% to 80% with the aid of PMMAPS. The PMMAPS was able to increase the haze of LSMs by improving the compatibility between PMMA and PS. Thus
LSMs with high haze and transmittance can obtained via alteration in the amount of PS and PMMAPS.
