摘要

In this work, β-polypropylene/polystyrene (β-PP/PS) blends were prepared with PP, PS, and a novel supported β-nucleating agent or β-nucleated PP and PS. The β-PP/PS blends were compatabilized by PP-g-MA, PP-g-GMA, POE-g-MA, and EVA-g-MA, respectively. For exploring the effect of PS amount and compatibilizers on the β-nucleation of PP, crystallization behavior and melting characteristics, the β-crystal content and crystal morphology of β-PP are characterized by differential scanning calorimetry (DSC), wide angle X-ray diffraction (WAXD), and polarized light microscopy (POM). The results indicated that the PP with high content of β-crystal was obtained by addition of CaCO _3 supported β-nucleating agent (β-NA) into PP. The β-nucleation, crystallization behavior, and melting characteristics, and the β-crystal content of β-PP in these blends were not influenced by addition of PS and its amount. However, the increased content of PS decreased the size of β-spherulites of PP in these blends. The β-nucleation of PP in compatabilized blends slightly depended on the compatibilizers. β-PP/PS blends with high β-crystal content can easily be prepared.
