| 摘要 |
<p>The present invention relates to a heterophasic polypropylene resin comprising
a propylene homo- or copolymer matrix (A) and an ethylene-propylene rubber phase (B) dispersed within the matrix,
wherein the heterophasic polypropylene resin has
a fraction insoluble in p-xylene at 25°C (XCU) with an intrinsic viscosity of 1.5 dl/g or less, determined according to DIN EN ISO 1628-1 and -3 and an amount of propylene monomer units of at least 95 mol%, and
a fraction soluble in p-xylene at 25°C (XCS) with an intrinsic viscosity of 1.5 to 3.0 dl/g, determined according to DIN EN ISO 1628-1 and -3, and an amount of propylene monomer units of 50 to 75 mol%,
and a MFR (2.16 kg, 230°C) of more than 100 g/10 min, determined according to ISO 1133, a heterophasic polypropylene composition comprising such a resin, a process for preparing that resin, and an article made thereof.</p> |
