Carbon fiber precursor composition and method for preparing carbon fiber precursor

[0047] 100 parts by weight of acrylonitrile (acrylonitrile, available from Sigma-Aldrich), 7 parts by weight of methyl acrylate (methyl acrylate, available from Sigma-Aldrich), 0.645 parts by weight of itaconic acid (itaconic acid, available from Sigma-Aldrich) Aldrich), 0.107 parts by weight of azobisisobutyronitrile (N,N'-azobisisobutyronitrile, purchased from Sigma-Aldrich), and 0.268 parts by weight of ethylenediamine (1,2-diaminoethane) dissolved in 429.6 parts by weight of di Methyl sulfoxide (dimethylsulfoxide, purchased from Tedia) to obtain a solution. Nitrogen gas was passed into the above solution and stirred, then heated to 70°C for reaction. After reacting for 24 hours, the resultant was poured into methanol (methanol), wherein the weight ratio of the resultant to methanol was 1:3. Next, the precipitate was collected to obtain a polyacrylonitrile-methyl acrylate-itaconic acid copolymer (as a carbon fiber precursor). The carbon spectrum of the obtained copolymer was
