Abstract
A process for the production of shaped articles of polyacrylonitrile, comprising wet spinning a solution, in a cold aqueous system as a coagulation bath, at a temperature not higher than 10º c, to form a filament, a film or other shaped article, said spinning solution being prepared by dissolving a polyacrylonitrile polymer in a concentrated inorganic acid as solvent, such as nitric acid, sulfuric acid or phosphoric acid, and, after washing with water, stretching said filament, film or other shaped article, up to at least 3 to more than 10 times its original length, at a temperature not higher than 110ºC but not lower than 60º c, under normal pressure, with water present on its surface.
