Light transmitance increases and haze decreases with the increase of the particle size of light difusion agent.
Our reseach results indicated the haze of PC was improved but its high light transmitance was maintained when 0.15wt% of light difusing agent was added.However，its impact strength decreased due to the presence of light difusing agent.Moreover，the masterbatch proces was found to be more efective than the direct melt-blending method. The anti-aging property of light-difusing PC was
significantly enhanced due to the presence of UV absorber.
