Abstract: The effects of triphenyl phosphate (TPP), resorcinol bis(diphenyl phosphate) (RDP), and PX on the flame retardancy of PC/ABS blends were studied.All the phosphate could improve the flame retardancy of PC/ABS blends effectively. Into a PC/ABS blend of weight ratio 7/3,11 wt% of TPP or 14 wt% of RDP or 12 wt% of PX was introduced, UL94 grade of V-0 could be obtained. In addition, the positive effect of a compatibilizer on the mechanical properties of PC/ABS alloy was also observed.
