| Abstract: | PBA-g-PS was synthesized via macromer techniques.Effect of polymerization conditions including charging weight ratio of polystyrene macromer,amount of initiator and temperature of copolymerization on grafting efficiency were studied.PBA-g-PS was used as compatibilizer in the blends of PS/ACR.Effects of composition of the blends,amount of the graft copolymer,and composition of the graft copolymer on mechanical properties were studied.The blends of PS/ACR were characterized with SEM and DSC.The results showed that the graft copolymers have the compatibilizing action on the blends. |

| Keywords: | polystyrene macromer graft copolymer compatibilizer mechanical property |
