摘要：

In order to prepare a polymer solution for making carbon fibre precusor by wetspinning,solution polymerization of acrylonitrile ( A N) with itaconic acid ( I A) was carriedoutin D M S Ousing azobisisobutyronitrile ( A I B N) asinitiator. The effects of( A N+ I A) and A I B N concentration , A Nto I Aratio,temperature on conversion rate and molecular weightwere investigated . The polymerization ratein D M S O was 2 .6 time as fast at thatin D M F. The copolymers were characterized by I Rand N M Ranalysis.
