Abstract
A heterophasic polyolefin composition comprising 55 to 95 wt.-% based on the total weight of the heterophasic polyolefin composition of a propylene butene random copolymer (A) having an MFR(230° C.) of 0.3 to 100.0 g/10 min and a butene content of 1.5 to 8.0 wt.-%, wherein the propylene butene random copolymer is obtained by a process using a single site catalyst (I) and 5 to 45 wt.-% based on the total weight of the heterophasic polyolefin composition of a copolymer of ethylene (B) having a density in the range of 910 to 935 kg/mand an MFR(190° C.) of 0.5 to 10 g/10 min, wherein the copolymer of ethylene (B) is obtained by a process using a single site catalyst (II).
