摘　　要：In order to improve the stabilization and spinnability of polyacrylonitrile, a bifunctional comonomer containing both ester and amide groups was synthesized to prepare poly（acrylonitrile-co-3- aminocarbonyl-3-butenoic acid methyl ester） [P（AN-co-ABM）] copolymers used as the carbon fiber precursor instead of poly（acrylonitrile-acrylamide-methyl acrylate） [P（AN-AM-MA）] terpolymer. The differential scanning calorimetry and thermogravimetry results show that the stabilization of P（AN-co- ABM） have been remarkably improved by ABM compared with P（AN-AM-MA） terpolymer, such as lower initiation temperature, broadened exothermic peak and smaller activation energy. Moreover, the spinnability of P（AN-co-ABM） is also improved by ABM due to the lubrication of ester groups in ABM. This study clearly shows that P（AN-co-ABM） copolymer is a better material for use as a carbon fiber precursor than P（AN-AM-MA） terpolymer.In order to improve the stabilization and spinnability of polyacrylonitrile, a bifunctional comonomer containing both ester and amide groups was synthesized to prepare poly（acrylonitrile-co-3- aminocarbonyl-3-butenoic acid methyl ester） [P（AN-co-ABM）] copolymers used as the carbon fiber precursor instead of poly（acrylonitrile-acrylamide-methyl acrylate） [P（AN-AM-MA）] terpolymer.
