Abstract (en)
[origin: WO03094832A2] The invention relates to a method for enhancing the fraction of ss-crystal modification in polypropylene by compounding nanocrystalline substances. A ss-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.
