制造硬度、韧性和可加工性改进的聚烯烃产物
摘要：
本发明描述聚合物以及制造与使用其的系统和方法。聚合物包括乙烯和至少一种具有4到20个碳原子的α烯烃。所述聚合物是通过微调催化剂系统形成，所述催化剂系统包括包含双(正丙基环戊二烯基)铪(R1)(R2)的负载型催化剂和包含内消旋‑O(SiMe2Ind)2Zr2(R1)(R2)的微调催化剂，其中R1和R2各自独立地是甲基、氯、氟或烃基。
摘要（英）：

Polymers, and systems and methods for making and using the same are described herein. A polymer includes ethylene and at least one alpha olefin having from 4 to 20 carbon atoms. The polymer is formed by a trimmed catalyst system including a supported catalyst including bis(n-propylcyclopentadienyl) hafnium (R1)(R2) and a trim catalyst comprising meso-O(SiMe2lnd)2Zr2(R1)(R2), wherein R1 and R2 are each, independently, methyl, chloro, fluoro, or a hydrocarbyl group.
