| 摘 要： | Synthesis of poly (methyl-methacrylate) (PMMA) in tetrahydrofuran at- 78℃ using al-kyllithium as initiator and its characterazation were studied. It was found that PMMA with harrow molecular weight distribution was obtained using 1,1-Kliphenyl-3-methylpentyllithium and 1,1-diphenyl-hexyllithium as initiators respectively. The sample of PMMA in the molecular weight (Mw) range from 1×104 to 2×106 had Mw'/Mn=1.06-1.20, its product possesses narrow molecular weight distribution and good symmetry, it achived level of PMMA standard sample and may be used it as GPC standard samples.
