Controlled rheology polypropylene heterophasic copolymers |
| 摘要 |
This invention relates to the use of a cyclic ketone peroxide of half-life time larger than one second at a temperature of 225° C., for producing a controlled rheology polypropylene heterophasic copolymer of melt index MI2 larger than 15 g/10 min, having simultaneously a very high impact resistance and a high flexural modulus.
