    摘要： Syndiotactic polypropylene blends having a unique set of mechanical properties may be prepared by blending syndiotactic polypropylene with a high molecular weight mineral oil, an ultra low density polyethylene, or both. The syndiotactic polypropylene blends of the present invention have been found to have reduced flexural modulus, reduced haze, improved impact strength and shorter injection molding cycle times. It has been determined that the addition of about 5 to about 10 percent high molecular weight mineral oil to a syndiotactic polypropylene can decrease flexural modulus values by about 25 to about 30 percent. Moreover, the addition of up to about 10 percent mineral oil to the syndiotactic polypropylene material does not show signs of bleeding or impair clarity, in fact, percent haze values are slightly improved with the addition of mineral oil. Additionally, injection molding cycle time optimization shows an improvement of about 12 seconds in overall cycle time utilizing a syndiotactic polypropylene blend with 5% mineral oil in comparison to a syndiotactic polypropylene without mineral oil. The syndiotactic polypropylene blends according to the present invention may be further processed according to accepted practices to make cast films, blown films, injection molded parts, blow molded containers, and other articles using basic plastics fabrication techniques as known in the art.

    摘要翻译： 具有独特机械性能的间同立构聚丙烯共混物可以通过将间同立构聚丙烯与高分子量矿物油，超低密度聚乙烯或两者混合来制备。 发现本发明的间同立构聚丙烯共混物具有降低的弯曲模量，降低的雾度，改进的冲击强度和较短的注塑周期时间。 已经确定，向间同立构聚丙烯中加入约5至约10％的高分子量矿物油可使挠曲模量值降低约25％至约30％。 此外，向间同立构聚丙烯材料添加高达约10％的矿物油不会出现渗血迹象或损害清晰度，事实上，通过添加矿物油，雾度值的百分比略有提高。 另外，与不含矿物油的间同立构聚丙烯相比，使用具有5％矿物油的间同立构聚丙烯共混物，注塑周期时间优化显示整个循环时间的改进约12秒。 根据本发明的间同立构聚丙烯共混物可以根据公认的做法进一步加工，以制备流延薄膜，吹塑薄膜，注模部件，吹塑容器和使用本领域已知的碱性塑料制造技术的其它制品。
