  • Heterophasic propylene copolymer with improved properties for injection molding applications
    Patent number: 8580890
    Abstract: The present invention concerns a heterophasic propylene copolymer of high melt flow for injection molding, which comprise a propylene polymer matrix and a rubber. The heterophasic propylene copolymers of the present invention are characterized by a high viscosity of the rubber phase and a well-defined ratio of the intrinsic viscosities of the rubber phase and the propylene polymer matrix, thus resulting in improved mechanical properties. The present invention further relates to a process for the production of such heterophasic propylene copolymers, their use and articles produced with them.
