The present invention relates to methods of producing syndiotactic polypropylene
articles through high performance nucleation via the presence of certain novel
nucleating agents within molten syndiotactic resins, and subsequently permitting
the resultant molten mixture to cool into a selected shape or configuration. Such
novel nucleating agents are new classes of hyper-nucleators that promote crystallization
within such target syndiotactic resins at levels well above any previously disclosed
nucleators. This invention thus also encompasses the articles and compositions
of such nucleated syndiotactic polypropylene as well.
