[54] HETEROPHASIC COPOLYMER
[57] Abstract: A heterophasic propylene ethylene copolymer having an MFR2 of 0.5 to 100 g/10min 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.
