| Abstract: | In this paper,chain transfer constant of graft copolymerization of SBS and MMA was determined.The influence on chain transfer constant of initiator concentration,reaction temperatures and solvents was discussed.The results show that chain transfer constant depends on reaction temperature and solvent.High temperature favors graft copolymerization,and enhances the efficiency of grafting. |
