Abstract

A process for the manufacture of fibers with flame-extinguishing properties, characterized by spinning in the form of fibers a copolymer composition comprising at least 85% by weight of copolymerized acrylonitrile, from 2 to 11% by weight of a forming monomer. fiber, copolymerized, neutral, ethylenically unsaturated, non-halogenated, and from 4 to 13% by weight of copolymerized bromopropene and where all the bromopropene is present in the form of a copolymer with acrylonitrile and the neutral monomer is present in the form of at least a copolymer selected from the group consisting of (a) said bromopropene copolymer with acrylonitrile and (b) acrylonitrile copolymers present with said neutral monomer, containing no halogenated monomer fractions; said copolymer composition being spun by dissolving it in a solvent and extruding the resulting solution in a coagulating bath.
