The dyeability of a polyolefin is improved by adding in up to 20% by weight a condensation polymer having triazole rings and represented by the formula <FORM:0939248/IV(a)/1> wherein R and R1 are methylene chain, cycloalkylene, benzene nucleus, heterocyclic ring, fused benzene nucleus or a derivative obtained by connecting two of any of these groups through a sulphonyl group; X and X1 are hydrogen, alkyl, benzene, fused benzene, pyrrole, pyridine, specified derivatives of said groups, or amino or various specified derivatives thereof, and n is from 1 to 200. The polyolefin may be polyethylene, polypropylene or polybutene. Of the many listed condensation polymers those preferred and exemplified are polytetramethylene triazole and/or aminotriazole, polyoctamethylene triazole and/or aminotriazole; benzol, naphthyl and formyl derivatives thereof; polycyclohexylene triazole, polypyridyl aminotriazole, polynaphthalenylene aminotriazole, polyphenylene methyl and acetamino triazoles and th condensation product of 4,41-(thiodiethylene)-dibenzoic acid dihydrazide. Solvents such as paraffin and polyethylene glycol may be used in forming the compositions. The examples illustrate the dyeing of filamentary products of the invention. |
