Abstract: | The effect of β-nucleation on structure and properties of cast films manufactured from isotactic polypropylenes has been studied. Two commercial-available polypropylenes - homopolymer and random copolymer were modified by 0.03 wt.% of specific β-nucleating agent NJ Star NU 100. Cast films were extruded from both starting and nucleated polypropylenes using a slit die and water-cooled chill roll. Supermolecular structure of the films was evaluated using wide-angle X-ray scattering. Tensile testing was used for the preliminary measurement of mechanical properties. A significant effect of the nucleation and solidification temperature on structure and properties of the films was found. |
