Novel polyolefin compositions and drawn tapes, fibres and filaments produced therefrom

摘要

The invention relates to a novel polyolefin composition which is suitable for producing drawn tapes, fibres and filaments which have improved mechanical properties. The composition comprises
A) 2 - 30 wt% of a propylene copolymer which comprises a
a) random propylene copolymer having a content of ethylene and/or C 4 -C 8 ±-olefin of 0.5 to 12 wt% and optionally an
b) ethylene-±-olefin rubber,
B) 70 - 98 wt% of a high density polyethylene having a density of 930 to 965 kg/m 3 and a MFR (190 °C/2.16 kg) of 0.3 to 20 g/10 min.
