摘　　要：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.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.
