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.
Synthesis of cyclohexyl cinnamate was studied by using PEG 400 and sulphuric acid as catalyst,cinnamic acid and cyclohexanol as raw materials.The effects of catalyst,reactants and reaction time were investigated under optimum conditions,the yield of cyclohexyl cinnamate was over 84.8%.
