The characteristics and product structures of homopolymerization of propylene oxide with \{Fe\|\}\{(acac)\-3\|Al( i \|Bu)\-3\} catalyst are presented and discussed. The polymer was characterized by \{\}\+\{13\}C\|NMR showing good stereospecificity.The polymer is a product of high alternation. The homoplymerization can be carried out in aromatic hydrocarbons and alkanes. The yield is higher in aromatic hydrocarbons than that in other solvents. The reaction kinetics was studied with catalyst of Al/Fe molar ratio 4～7. The results indicate that apparent rate of homoplymerization reaction is first order with respect to monomer concentration, and the energy of activation equals 158.1 kJ/mol.
The characteristics and structure of the titled copolymer are presented and discussed in the present paper.The copolymer is characterized by IR and 1H NMR.The copolymer is a product of high alternation.The content of meleic anhydride is 47% in the copolymer.The copolymerization can be realized in solvents such as aromatic hydrocarbon and alkane.The yield is higher in aromatic hydrocarbon than that in the others.The suitable Al/Fe molar ratio is 2～6.The suitable Fe/ α,α′ dipyridyl molar ratio is 1.From kinetic studies the activation energy of copolymerization is evaluated to be 89 6 kJ/mol.
