Two kinds of polymeric stabilizer containing benzophenone and hindred amine group have been synthesized. The effect of compatibility of polymeric stabilizer in polypropylene on the light stable efficiency has been studied. We found that the light stable efficiency depends on the difference of solubility parameter betweeh polymeric stabilizer and polypropylene. The smaller the difference of solubility parameter it has
the higher the light stable efficiency it becomes.
