Melt spinninig on twin screw extruder - Part II: Polyolefin elastomer fibers by means of reactive extrusion

One way to modify polymers and to produce synthetic fibers in a single cont inuous extrusion step is the connection of reactive extrusion and melt spin ning where the tailor-made modification and the fibre formation can be carr ied out simultaneously. In the first part of the contribution the technolog ical requirements and goals were discussed. In the second part of the paper we present some variations concerning the thermal and mechanical propertie s of elastomeric ethylene-octene-copolymer fibers, which could be achieved by a chemical crosslinking via graftpolymerised vinyl-silane.
