摘要:
A heterophasic propylene ethylene copolymer having an MFR2 of 0.5 to 100 g/10 m in and obtained using single site catalysis comprising: (i) a propylene homopolymer or propylene ethylene copolymer matrix having up to 4 wt % ethylene; and (ii) an ethylene propylene rubber (EPR) dispersed in the matrix; said heterophasic propylene ethylene copolymer having a xylene cold soluble content (XS) of 20 to 40%; wherein the ethylene content of the xylene cold soluble fraction of said heterophasic propylene ethylene copolymer is between 70 and 90 wt. %; wherein the xylene cold soluble fraction of said heterophasic propylene ethylene copolymer has an intrinsic viscosity (IV) of 3.0 dl/g or more; and wherein the melting enthalpy (ΔHM) of the heterophasic propylene ethylene copolymer is between 10 and 30 J/g at a temperature of 0 to 130° C.
