Resinous compositions which are spinnable comprise a crystalline polyolefin or an acrylonitrile polymer or copolymer and from 1 to 25% of a resinous condensation product of epichlorohydrin and an amine. The resinous condensation products may be prepared by the condensation of epichlorohydrin with a primary or secondary amine or a salt thereof, preferably in the presence of an alkaline condensing agent such as the hydroxide or carbonate of an alkaline earth or alkali metal and, if desired, in the presence of an inert solvent such as ethyl alcohol. The resinous condensation products may have been further reacted with another amine, an alkyl halide, an aryl halide or an aliphatic imine such as ethylene imine. The compositions may also contain solid dispersing agents of which many are specified including cetyl and stearyl alcohol, stearic acid, terephthalic acid, benzoin, furion, vinyl stearate, glycerol mono-, di- and tristearates, ethanolamine stearate, stearamide, N-diethanollauramide, C6-C30 aliphatic amines, condensation products of ethylene oxide with alcohols, amines and phenols, polystearamide, polyacrylic acid polystyrene, styrene copolymers and terpene polymers. The acrylonitrile polymer or copolymer compositions may contain spinning solvents, e.g. dimethylformamide, g -butyrolactone or ethylene carbonate. The compositions may be spun into fibres and the resinous condensation product may then be cross-linked by, for example, formaldehyde, an isocyanate such as hexamethylene diisocyanate, a diepoxide such as the diglycidyl ether of ethylene glycol in water, or divinylbenzene. In examples the following resinous condensation products are prepared from the first two reactants named and modified by the third: octadecylamine / epichlorohydrin/hexamethylenediamin (1, 8 and 23); dodecylamine / epichlorohydrin / 1, 2-propylenediamine (2); dodecylamine / epichlorohydrin / triethylene-tetramine (3); dodecylamine / epichlorohydrin/tetraethylenepentamine (4); octadecylamine/epichlorohydrin / tetraethylenepentamine (5); dodecylamine / epichlorohydrin / hexamethylenediamine (6); octadecylamine / epichlorohydrin (9); octadecylamine / epichlorohydrin / hexamethylenediamine and triethylenetetramine (10); hexamethylenediamine / epichlorohydrin / octadecyl chloride (16 and 17); hexamethylenediamine / epichlorohydrin / cetyl, lauryl, or benzyl chloride (17); octadecylamine / epichlorohydrin/ethylene imine (18 and 19); dodecylamine / epichlorohydrin / ethylene imine (20); dioctadecylamine / epichlorohydrin / ethylene imine (21); dodecylamine / epichlorohydrin / ethylenediamine (24). Spinning compositions comprising one of the above resinous products or the reaction product of aniline and epichlorohydrin with crystalline polypropylene, low-pressure polyethylene, polyacrylonitrile, an acrylonitrile/methyl methacrylate copolymer or an acrylonitrile/ethyl acrylate copolymer are also described. The solubility of the condensation product of Example 1 in many solvents is given.ALSO:Fibres spun from compositions comprising a crystalline polyolefin, or an acrylonitrile polymer or copolymer and from 1 to 25% by weight of the polymer or copolymer of a resinous condensation product of an amine and epichlorohydrin may be dyed by means of acid dyes, acetate dyes, basic dyes, metallised dyes, plastosoluble dyes and vat dyes.
