Abstract:
The invention relates to a creep-optimized ultrahigh molecular weight polyethylene (UHMWPE) fiber obtained by spinning an UHMWPE comprising olefinic branches (OB) and having an elongational stress (ES), and a ratio (OB/1000 C/ES) between the number of olefinic branches per thousand carbon atoms (OB/1000 C) and the elongational stress (ES) of at least 0.2, wherein said UHMWPE fiber when subjected to a load of 600 MPa at a temperature of 70° C., has a creep lifetime of at least 90 hours.
