There are disclosed dyeable fibers comprising mixtures of olefinic polymers with terpolymers of (a) vinyl or isopropenyl derivatives of aromatic hydrocarbons, such as styrene, vinyl-toluene, alpha-methylstyrene and the like; (b) alpha, beta-unsaturated nitriles, such as acrylonitrile, methacrylonitrile, and the like; and (c) aromatic and cycloaliphatic hydrocarbons, containing a double vinylenic bond, such as indene, acenanaphthylene, cyclohexene, and the like. The olefin polymer may be, and preferably is, a high molecular weight polypropylene consisting essentially of isotactic polypropylene made up of isotactic macromolecules, i.e., of macromolecules having substantially isotactic structure and being non-extractable with boiling n-heptane. A process for preparing the dye-receptive fibers is also disclosed. |
