Zusammenfassung: | A heterophasic propylene ethylene copolymer having an MFR2 of 0.5 to 100 g/10 min and obtained using single site catalysis comprising: (i) at least 40 wt % of a propylene homopolymer or propylene ethylene copolymer matrix having up to 4 wt % comonomer; (ii) at least 10 wt % of an ethylene propylene rubber dispersed in the matrix, said heterophasic propylene ethylene copolymer having a xylene cold soluble content (XS) of 12 to 60%; wherein the ethylene content of the xylene cold soluble fraction of said heterophasic propylene ethylene copolymer is between 18 and 70 wt. %; and wherein the intrinsic viscosity of the XS fraction of said heterophasic propylene ethylene copolymer is greater than the intrinsic viscosity of the matrix fraction of said copolymer. |
