Abstract
This invention relates to the production of spinnable solutions of acrylonitrile homopolymers or acrylonitrile copolymers in which the polymerization is conducted in an organic solvent containing a catalyst system comprising an acid, e.g., sulfuric acid, a peroxodisulfate, e.g., ammonium peroxodisulfate, and a 1,3-diketone, e.g., acetyl acetone. Polymers having a good natural color and high K-values are obtained in good yields.
