  • Patent number: 9701801
    Abstract: A process includes combining a metallocene catalyzed polypropylene with a nucleator and a slip agent to form a composition, and forming a cast film from the composition. The slip agent may exhibit an increased slip bloom rate within the cast film relative to the slip bloom rate exhibited by the slip agent in an otherwise identical cast film in which the nucleator is not present in the cast film. The cast film may exhibit a coefficient of friction that is less than a coefficient of friction of an otherwise identical cast film in which the nucleator is not present in the cast film.

  • Publication number: 20140200293
    Abstract: Disclosed is a polystyrene based polymer/layered compound nanocomposite for injection blow molding or injection stretch blow molding of articles. The nanocomposite can reduce shrinkage and warpage to the preform during the reheating process compared to neat polystyrene. The incorporation of layered compounds can increase the processability of PS preforms, help improve heating efficiency, and improve bottle mechanical properties. The layered compound can be treated with chemicals or compounds having an affinity with the styrene monomer or polystyrene, thus producing a treated layered compound having an affinity with the styrene monomer or polystyrene. The monomer and the layered compound can be combined prior to polymerization. The polymer and layered compound can be combined by solution mixing in a solvent.
