Polystyrene g polymethylmethacrylate with controlled molecular weight and lower polydispersity was obtained by using anionic polymerization, group transfer polymerization (GTP) and polymer reaction. First, NDPS (PS with narrow n distribution) prepared by anionic polymerization was chloromethylated by methylal and sulfurylchloride to form chloromethylation polystyrene (CMPS); and then, CMPS dissloved in THF whose impurity was removed by sodium naphthalene, coupled with living polymer of PMMA prepared by GTP. The copolymer was characterized by 1HNMR. FT IR and GPC. The n and D of copolymers were 1×10 4～3×10 4 and 1.08～1.20 respectively.
