研究了聚丙烯（PP）-反式1,4-聚丁二烯（PBD）共混物的结构和机械性能。 发现PBD可以在PP上外延结晶。 尽管纯 PBD 的机械性能比 PP 差得多，但观察到机械性能（杨氏模量、断裂应力）有所增加。 外延形貌负责机械性能的协同效应。
The structure and mechanical properties of polypropylene (PP)-trans-1,4-polybutadiene (PBD) blends were investigated. It was found that PBD can epitaxially crystallize on PP. An increase in mechanical properties (Young's modulus, fracture stress) is observed, despite the fact that pure PBD has much worse mechanical properties compared to PP. The epitaxial morphology is responsible for the synergetic effects in the mechanical properties.
