  The present invention relates to a process for the production of polyacrylonitrile by polymerisation of a reaction mixture comprising acrylonitrile in a solution where the solvent is a eutectic system comprising a quaternary ammonium compound and a hydrogen donor. Such process allows for the production of a polyacrylonitrile having a desirably high molecular weight, whilst polymerisation time is reduced, and where the solvents are environmentally benign, biodegradable and may be reused in the polymerisation process.
