Abstract

Process for obtaining fibers, modacryl yarns protected against flames, with improved thermostability, characterized in that 35 to 85% by weight of acrylic nitrile are copolymerized, 5 to 45% by weight of vinyl chloride, vinyl bromide and/or vinylidene chloride, 5 to 30% by weight of carboxyphosphinic acid derivatives of Formula I ** (See formula) ** in which R1 and R2 represent halogenated alcohol or alcohol radicals with no more than 8 carbon atoms, R3 a hydrogen atom or a methyl group, X an oxygen or sulfur atom, a Y an optionally branched alcoholic group, with 1 to 6 carbon atoms, and 0 to 15% by weight of other unsaturated compounds with activated double bond, always in relation to the total amount of the monomer, the polymeric products obtained being dissolved in aprobic solvents, or the spinning solutions thus obtained being spun in threads or fibers, eventually after adding other auxiliary substances.
