Abstract
Solvent system for polyacrylonitrile polymers comprising nitromethane, water and fluoro alkanol. The solvent enables a high concentration of polymer to be dissolved without the solution being too viscous to cast as a film or to spin as a fiber. The solvent is sufficiently soluble that it can be removed substantially completely from the resulting film or fiber with consequent advantages of leaving no toxic residue and of not discoloring the end product.
