Abstract
Novel melt-spun elastomeric fibers and methods for their preparation. Embodiments are provided in which fibers are melt-spun from a melt-spinnable elastomeric polymer comprising a diisocyanate-capped polyol prepolymer which is chain-extended with an aromatic dihydroxy compound. Also provided are melt-spinnable elastomeric polymers and prepolymers therefor. The fibers may be knit or woven into textile articles including, inter alia, hosiery and pantyhose.
