Abstract
Process for obtaining polyacrylonitrile solutions, characterized in that it comprises dissolving acrylonitrile, together with one or more copolymerizable compounds, when these are used, in a concentrated solution of an inorganic thiocyanate, and polymerizing the monomer or monomers in the solution, in the presence of a non-oxidizing and free radical-forming azo polymerization catalyst, the ph value of the solution being maintained between 3.5 and 5.5 during the polymerization.
