| Abstract: | The suspension graft copolymerization of polycarbonate (PC) with styrene (ST) was studied. Effects of various parameters such as the ratio of ST to PC, initiator concentration and reaction time on the graft copolymer were investigated. The graft copolymer with grafting degree of 35% and grafting efficiency of 65% was synthesized. The graft copolymers have been characterized by IR, DSC and DMA. The molecular weight and the number of branched chain(PS)in graft copolymers were measured. |
