Beschreibung
Zusammenfassung:	The present invention relates to a heterophasic propylene polymer (HECO) comprising a) 65 to 90 wt. % of a matrix component (M) selected from a propylene homo- or random copolymer (PP); and b) 10 to 35 wt. % of an ethylene-propylene rubber (EPR), dispersed in the propylene homo- or random copolymer (PP), whereby the xylene cold soluble fraction (XCS) of the heterophasic propylene polymer (HECO) has-an ethylene content of 10.0 to 17.0 wt. %; -an intrinsic viscosity (IV), determined according to ISO 1628-1:2009, of at least 1.6 dl/g; and the xylene cold insoluble fraction (XCI) of the heterophasic propylene polymer (HECO) has 2, 1-erythro regiodefects in an amount of at least 0.4 mol % to a composition comprising the heterophasic propylene polymer (HECO), a process for its preparation and an article comprising the heterophasic propylene polymer (HECO) or the composition comprising the same.
