ABSTRACT:
A polyacrylonitrile fiber which has flame-retardant properties, is produced by dry spinning, has an acrylonitrile content of at least 85% by weight in the parent polymer and contains as flame retarder 15 to 40% by weight of tris-2,3-dibromopropyl isocyanurate, based on the polymer. The flame-retardant effect can be further increased by a content of up to 10% by weight of one or more synergistic compounds.
