The polymerization of MMA catalyzed by bridged lanthanocene amide as single compoent catalyst has been investigated. The polymers obtained were characterized by GPC, FT IR, 1H NMR and DSC. The results indicated that the conversion and the molecular weight decreased with decrease in polymerization temperature. The PMMA obtained was mainly in syndiotactic structure.
