    摘要: The present invention relates to a heterophasic polyolefin composition having improved flowability and impact strength but also an excellent impact/stiffness balance and a low amount of a hexane extractable fraction, to a process for its preparation, articles made therefrom and uses thereof. The heterophasic polyolefin composition comprises a matrix comprising a propylene homo- and/or copolymer, and an elastomeric ethylene/alpha-olefin phase dispersed in the matrix, the heterophasic polyolefin composition comprising monomer units derived from an oligomeric diene compound, wherein the heterophasic polyolefin composition has a tensile modulus of at least 1600 MPa, measured according to ISO 527-2, a puncture energy determined in instrumented falling weight at 23 °C according to ISO 6603-2 of at least 15.0 J, a Charpy notched impact strength of at least 4.0 kJ/m 2 , determined according to ISO 179/1eA:2000 at 23 °C, and a MFR (2.16 kg, 230 °C, ISO 1133) of at least 50 g/10min. The heterophasic polyolefin composition may be used for any conversion processes for thermoplastic polymers, especially injection moulding.
