Aq. acrylonitrile polymer soln.(I) contg. thiocyanate and amide for manufg. high nonflammable products such as fiber or film from acrylonitrile copolymer consisted of halogenized vinyl or vinylidene. Thus, acrylonitrile copolymer consisting of 10-50 wt.% halogenized vinyl and/or vinylidene was dissolved in mixed solvent of thiocyanate 30-60, H2O 25-55, org. compd. I, II, or III 5,45wt.% to give I.
