ABSTRACT
ADVANTAGES. Topanol CA/ESTDP/phosphite combinations, being highly synergistic provide more effective processing and life stabilization (Fig. 13). 4. Polystyrene
Impact polystyrene, contaInIng 5-150/0 butadiene rubber", requires significant antioxidant additions. Clear (crystal) polystyrene and foam polystyrene use minimal amounts of antioxidant (usually BHT).
