  • Highly active ?-nucleating additive for polypropylene
    Patent number: 6992128
    Abstract: The invention relates to a method for enhancing the fraction of ?-crystal modification in polypropylene by compounding nanocrystalline substances. A ?-fraction of 50–100% is achieved with said method. The compounds are characterized by improved mechanical properties. The nanocrystalline powders can be directly compounded and compatibilized with surface-active substances in the PP matrix for better dispersion.
