Abstract
"Process for dyeing synthetic polymers", especially polyacrylonitrile and its copolymers in order to allow its dyeing by acid dyes, characterized in that the polyacrylonitrile or its copolymers are mixed in solution with appreciable amounts of aliphatic mono- or diamines primary, secondary or tertiary containing in its molecule at least 10 carbon atoms, in the presence of mineral substances of acid nature.
