| 摘要 |
The present invention relates to a heterophasic polypropylene resin comprising a polypropylene homo- or copolymer matrix phase (A) and an ethylene-propylene copolymer phase (B) dispersed within the matrix,
wherein the heterophasic polypropylene resin has
a fraction insoluble in p-xylene (XCU) at 25°C with an intrinsic viscosity of 2.0 dl/g or less, determined according to DIN EN ISO 1628-1 and -3, and
a fraction soluble in p-xylene (XCS) at 25°C having an intrinsic viscosity of 2.0 to 4.5 dl/g, determined according to DIN EN ISO 1628-1 and -3, and an amount of ethylene monomer units of 60 to 85 mol%, a heterophasic polypropylene composition comprising such a resin, a process for preparing that resin, and an article made thereof. |
