The preparation technology of flame-retardant PC/ABS alloys was studied in
this paper. Using a high-efficiency flame retardant system and by means of
multiple-ingredient compatibilizing, PC/ABS alloys with excellent impact st
rength and flame retardant property were prepared. The experimental results
showed that by using PS-g-MAH and SMA as synergistic compatibilizers, the
notched Izod impact strength and flammability of PC/ABS alloy obtained in t
he present work can be up to 175 J/m and UL-94 VO, respectively.
