Abstract
"Process for dyeing synthetic polymers", especially polyacrylonitrile and its polymers in order to allow its dyeing by acid dyes, characterized in that the polyacrylonitrile or its copolymers are reacted in solution with appreciable amounts of organic nitrogenous bases, aliphatic or alicyclic, primary or secondary, having a maximum of 10 carbon atoms in its molecule, in the presence of a sulfonic acid and, eventually, other substances of an acidic nature.
