  • For producing propylene polymers that are suited for fiber spinning
    Publication number: 20030236378
    Abstract: A process for producing from propylene, ethylene and/or C4-C18-alk-1-enes a fiber grade propylene polymer in which not less than 90 mol % of the units derived from monomers are derived from propylene and which has a polydispersity index PDI of not more than 2.2, where PDI is MW/MN, where MW is the weight average molar mass and MN is the number average molar mass and both are determined by gel permeation chromatography (GPC) at 145° C. in 1,2,4-trichlorobenzene, by polymerizing the monomers by means of a metallocene catalyst system, comprises subsequently degrading said propylene polymer peroxidically or thermally.
