    • PURPOSE: To obtain the titled synthetic fibers having improved luster, transparancy and flame retardancy, by spinning a solution containing a polymer consisting of acrylonitrile, a monomer containing a halogen and a copolymerizable monomer in a specific composition, an organotin compound and an organic solvent.
      CONSTITUTION: A solution containing (A) a polymer consisting of (a) 30W70wt% acrylonitrile, (b) 70W30wt% monomer containing a halogen, e.g. vinyl chloride, and (c) 0W10wt% one or more olefinic monomers copolymerizable therewith, e.g. acrylamide, (B) an organotin compound, e.g. dibutyltin ethylmaleate, and (C) an organic solvent, e.g. dimethylformamide, as a spinning solution is spun to give the aimed fibers having improved luster and transparancy. The amount of the component (B) is preferably 0.2W10wt% based on the component (A).
