Paper Title:
Novel Method to Toughen Polypropylene by Uniaxial Compression Processing
  Abstract

Based on the orientation of molecule chain in fibers, it will urge a rapid increase in mechanical properties. Nevertheless, block materials mainly gain rise of mechanical properties by blend or composite today, it is hardly proposed on self-toughening materials by optimizing the microstructure because of a lack of relations between the performance and the microstructure in block materials. In this paper, a toughening PP was gained through small deformation of spherulite, processed by uniaxial compression. A series of measurements were applied, including impact test and polarizing optical microscope (POM). The results show that the impact properties of polypropylene (PP) have a rapid rise. POM suggests that the spherulite has deformed into ellipsoid even belt along the orientation of sample of PP, which plays an important role in toughening.
