摘要：

In order to prepare a polymer solution for making carbon fibre precusor by wet spinning, solution polymerization of acrylonitrile (AN) with itaconic acid (IA) was carried out in DMSO using azobisisobutyronitrile (AIBN) as initiator. The effects of (AN + IA) and AIBN concentration, AN to IA ratio, temperature on conversion rate and molecular weight were investigated. The polymerization rate in DMSO was 2.6 time as fast at that in DMF. The copolymers were characterized by IR and NMR analysis.
