    Abstract: Dyeable (especially cationic-dyeable) acrylonitrile (AN) compositions and articles (e.g., films and filaments) are produced from blends of (I) a particular ternary or higher multicomponent AN polymer and (II) a copolymer of vinyl acetate and N,N-dimethylacrylamide wherein the latter constitutes from 1 to 90 percent by weight of the said copolymer. The polymer of (I) contains at least three different copolymerized monomers of the kind and in average percent mers, based on the total number of mers from individual monomers employed in making the copolymer, as follows: A. from 85 to 99 percent AN; B. from 1 to 14.5 percent of A. A VINYLIDENE HALIDE, OR B. A DYE DIFFUSION-PROMOTING, ETHYLENICALLY UNSATURATED MONOMER THAT IS COPOLYMERIZABLE WITH THE OTHER COMPONENTS OF THE COPOLYMER, E.G., VINYL ACETATE, ACRYLIC AND METHACRYLIC ACIDS, METHACRYLONITRILE, METHACRYLAMIDE, N-isooctylacrylamide, N,Ndimethylacrylamide, diacetone acrylamide and the monoallylether of trimethylolpropane, and C. from 0.15 percent to about 2 percent of a water-soluble salt of an organic sulfonic acid, e.g., vinylsulfonic, allylsulfonic, methallylsulfonic acids, and especially organic sulfonic acids wherein the sulfo group is separated from the ethylenic unsaturation by at least three carbon atoms, e.g., styrenesulfonic acid. The total of A, B and C is 100 percent. The amount of the copolymer of (II) that is blended with the AN polymer of (I) is, for example, from 2-15 wt. percent of the total of (I) and (II). The components may be dry-blended, but are preferably blended while dissolved in a common solvent, e.g., dimethylacetamide, The solutions can be cast to form cationic-dyeable films or wet-spun to form cationic-dyeable filamentary materials and other shaped articles.

    Abstract: AN ADDUCT COMPOSITION PARTICULARLY USEFUL FOR INCREASING THE DYEABILITY OF SHAPED POLYMERIC ARTICLES, PARTICULARLY FIBERS AND MORE PARTICULARLY, ACRYLONITRILE FIBERS. THE COMPOSITION IS AN ADDUCT OF A POLYMER OF A CYCLIC ETHER AND A SULTONE. THE ADDUCT FUNCTIONS AS A DYESITE FOR A CATIONIC DYE DIFFUSION PROMOTER WHEN INCORPORATED INTO A POLYMER. THE METHOD OF PRODUCING SUCH ADDUCTS IS ALSO DESCRIBED.
