摘要	Products obtained by reacting polymers or copolymers of conjugated dienes with sulphur dioxide are rendered easier to dye by treatment with a cation-active compound which may be cetyl pyridinium bromide or chloride, cetyl trimethyl ammonium bromide, triethyl octadecyl oxymethyl ammonium chloride, cetyl ammonium chloride, cetyl dimethyl sulphonium bromide, cetyl dimethyl sulphonium methyl sulphate, or a sapamine. The reaction products are preferably treated, prior to dyeing, with a swelling agent which may be chloroform, dichloro-ethane, acetone, ethanol, sulphuric acid, phosphoric acid or zinc chloride. The conjugated diene may be butadiene, methyl butadiene, dimethyl butadiene or chloroprene, which substances may be copolymerized with each other or with isobutylene, styrene, vinyl chloride, vinyl esters, acrylic acid, methacrylic acid, acrylonitrile or methacrylonitrile. The reaction products to be treated may also comprise products obtained by the reaction of the polymers or copolymers and unsaturated compounds of low molecular weight with sulphur dioxide, suitable low molecular weight compounds being butadiene, 1,5-hexadiene, allyl alcohol, chloride, acetate, capronate, isothiocyanate, and oleate, diallyl phthalate and diallyl adipate. The treated polymers may be used in the preparation of threads, fibres, fabrics, tapes and films. Specification 666,644, [Group V], is referred to.
