Abstract

1. A method for producing fibers from a thermoplastic polymerisate of acrylonitrile with esters of acrylic or methacrylic acid, which polymer has a molar concentration of acrylonitrile units in the range of 50 to 96 %, characterized in that a graft polymerisate of acrylonitril/acrylic or methacrylic acid ester grafted on a copolymerisate of acrylonitril/butadiene and/or -isoprene or of acryloacrylates is used as polymerisate, said polymerisate is extruded to strips or tubes, said strips or tubes are uniaxially stretchend at temperatures between 100 and 150 degrees C and are split after cooling.
