Preparation method of acrylonitrile copolymer for carbon fiber |
| abstract |
The present invention provides a preparation method of an acrylonitrile-based copolymer for carbon fibers, the preparation method comprising: preparing a reaction solution including a monomer mixture including the sulfonates represented by Chemical Formula 1 and an organic solvent monomers, carboxylic acid-based monomers, and acrylonitrile-based monomers; and polymerizing the reaction solution, wherein the monomer mixture contains 0.55 mol % to 1.6 mol % of the sulfonate salt represented by Chemical Formula 1 class of monomers. |
