    摘要： The invention relates to a process for the preparation of a heterophasic polypropylene resin in a multistage polymerisation process in the presence of a metallocene catalyst, said process comprising: (I) in a first polymerisation step, polymerising propylene and optionally at least one C2-10 alpha olefin comonomer; and subsequently (II) in a second polymerisation step, polymerising propylene, ethylene and optionally at least one C3-10 alpha olefin comonomer, in the presence of the metallocene catalyst and polymer from step (I); wherein step (II) takes place in at least one gas phase reactor operating at a pressure of at least 26 bar. The present invention further relates to a heterophasic polypropylene resin comprising a polypropylene matrix phase (A) and an ethylene-propylene copolymer phase (B) dispersed within said polypropylene matrix phase, wherein the ethylene-propylene copolymer phase (B) is an amorphous ethylene-propylene copolymer with an intrinsic viscosity (iV) measured in decalin at 135° C. of at least 3.5 dl/g and an ethylene content of at least 15 wt % of the total weight to the ethylene-propylene copolymer, comprising at least 4 long chain branches (LCB) per copolymer chain.
