The invention relates to polyolefin compositions with high impact strength and high gloss,ncomprisingn A) a heterophasic propylene copolymer containingn a) 50 - 95 wt% of a matrix phase comprising a propylene homopolymer or anpropylene copolymer with up to 5 mol% of ethylene and/or at least onenC 4 -C 8 α-olefin and b) 5 - 50 wt% of a disperse phase comprising an ethylene rubberncopolymer with from 20 - 80 mol% ethylene and from 80 - 20 mol% of atnleast one C 3 -C 8 α-olefin and where the intrinsic viscosity of the XCS-fractionnof the heterophasic copolymer is ≤ 2 dl/g and B) a β-nucleating agent and a process for their preparation and their use. |
