In this paper, the effects of antioxidants and processing parameters on the thermal stability and processability of sPS have been investigated. Experimental results indicate that a long processing duration and mechanic shearing force accelerate the thermal oxidation and addition of antioxidants into sPS can effectively improve color contamination and thermal stability. Furthermore, feasible estimation of sPS/PPO alloys for reflective cups of light emitting diodes (LEDs) have also been made, demonstrating that sPS/PPO alloys are potential candidates by the appropriate prescription of impact modifiers, flame retardants, and titanium dioxide.
► The effects of antioxidants and processing parameters on the thermal stability and processability of sPS have been investigated. ► With appropriate antioxidants, color contamination and thermal stability of sPS have been improved. ► sPS/PPO alloys are potential materials for reflective cups of LEDs with proper recipes of TiO2, antioxidants, impact modifiers, and flame retardants.
