FIBRES CREUSES A PAROI MICROPOREUSE |
摘要 |
<p>A hollow fibre is provided possessing a continuous longitudinally extending channel free from macromolecular material, said fibre consisting essentially of a copolymer of acrylonitrile and an olefinically unsaturated comonomer containing an optionally salified sulphonic acid group, and possessing micropores of average diameter less than about 100 A, between 40 and 80% of walls of the fibre being empty space. This fibre can be prepared by injecting a solution of a copolymer of acrylonitrile and an olefinically unsaturated comonomer containing an optionally salified sulphonic acid group in at least one polar organic solvent into a spinneret with an annular orifice, and immediately coagulating the inside and the outside of the nascent hollow fibre issuing from the spinneret with a coagulating fluid which is selected from:</p> |
