Abstract:
The present invention relates to a polyethylene homo- or copolymer having improved wear properties. In particular, the invention relates to an ultra-high molecular weight polyethylene having improved wear properties prepared using a heterogeneous Ziegler catalyst system. Said polyethylene homo- or copolymer is characterized in that the abrasion index of said polyethylene is related to the elongational stress according to the formula (I): in which ES=elongational stress as measured according to ISO 11542-2:1998 AI=abrasion index, as measured according to ISO 15527:2010 where the reference material according to ISO 15527:2010 is set to 100; β
