The polymerization of MMA by coordination catalyst of Nd(naph) 3 Al(i Bu) 3 α,α’ Dipyridyl was described in this paper.Characterization of the structure of the polymer is revealed by NMR and IR.These studies revealed that the polymer obtained has mainly syndiotactic and shetero structures.Molecular weight and distribution are studied by GPC.Coordinate mechanism was proposed for the MMA polymerization by Nd Al α,α’ Dipyridyl.Kinetic studies showed that the MMA polymerization rate is first order with respect to monomer concentration.The apparent activation energy of MMA polymerization reaction is 22.2 kJ/mol.
