Abstract

Improvements introduced in the object of the main Patent No. 235,147, that is in a process for the manufacture of spinnable solutions from acrylonitrile polymers by polymerization of monomers dissolved in aqueous nitric acid with a NO3H content of 55-68% by weight , characterized in that the polymerization is carried out in the presence of a catalyst system, consisting of peroxy compounds and metallic dicarbonyl compounds.
