Production method of polyacrylonitrile |
| abstract |
The present invention relates to a process for the production of polyacrylonitrile by polymerizing a reaction mixture comprising acrylonitrile in solution, wherein the solvent is a eutectic system comprising a quaternary ammonium compound and a hydrogen donor. This method allows the production of polyacrylonitrile with the desired high molecular weight with reduced polymerization time, and in which the solvent is environmentally friendly, biodegradable and can be reused in the polymerization process. |
