| Zusammenfassung: | The invention relates to a method for enhancing the fraction of β-crystal modification in polypropylene by compounding nanocrystalline substances. A β-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. |
