    摘要: The present invention relates to an acrylonitrile copolymer comprising 70% by weight or more of an acrylonitrile monomer unit and 0.1-30% by weight of a fluoroalkyl methacrylate or fluoroalkyl acrylate monomer unit and having an intrinsic viscosity of 0.8-10, as well as to an acrylonitrile type core-sheath conjugate fiber using the above copolymer as the sheath component. The copolymer according to the present invention has water repellency by itself; accordingly, the above conjugate fiber prepared therefrom also exhibits water repellency permanently.
