Procedure

95 mol % of acrylonitrile, 3 mol % of methacrylic acid and 2 mol % of itaconic acid were polymerized by solution polymerization using dimethylsulfoxide as a solvent, and then ammonia was added thereto in an amount equivalent to that of itaconic acid to neutralize the reaction product to prepare a polyacrylontrile-based copolymer in the form of an ammonium salt, thereby obtaining a spinning solution including 22 wt % of the polyacrylontrile-based copolymer.
