  • Polypropylene impact copolymers with low haze
    Patent number: 10808111
    Abstract: The present invention provides an in-reactor solution that avoids costly blending and the use of metallocene elastomers. The inventive Ziegler-Natta polypropylene composition also includes additional components that may improve properties relative to a metallocene catalyzed elastomers. The invention is a clear impact polypropylene composition that is made in-reactor with Ziegler-Natta catalyst, and is suitable for a wide range of processes. Unlike other clear impact copolymers, it does not rely on high-shear processes or compounding with elastomers. The invention uses conventional polypropylene reactor technology to produce these compositions.
