The characteristics and structure of the titled copolymer are presented and discussed in the present paper.The eopolymer is characterized by IR and 1H-NMR.The copolymer is a product of high alternation.The content of meleie 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 inthe others.The suitableAl/Fe emolar ratiois 2~6.The suitableFe/a
a'-dipyridylmolar ratioisl.From kinetic studies the activation energy of eopolymerization is evaluated to be 89.6 kJ/mol.
