AB  - Blending octene random copolymer (ORC) with other polymers is a promising 
      approach to improving ORC mechanical properties, such as tensile strength and 
      elongation. In this study, octene block copolymer (OBC) with lower density than 
      ORC and high-density polyethylene (HDPE) were used to blend with ORC. The effect 
      of both OBC and HDPE on ORC was analyzed using scanning electron microscopy 
      (SEM), differential scanning calorimetry (DSC), dynamic mechanical analysis (DMA) 
      and small-angle X-ray scattering (SAXS). For ORC/OBC blends, a small amount of 
      OBC can improve the crystallization ability of ORC. Meanwhile, for ORC/HDPE 
      blends, the crystallization ability of ORC was significantly suppressed, 
      attributed to good compatibility between ORC and HDPE as indicated by the 
      homogeneous morphology and the disappearance of the alpha transition peak of ORC in 
      ORC/HDPE blends. Therefore, the tensile strength and elongation of ORC/HDPE 
      blends are significantly higher than those of ORC/OBC blends. For ORC/OBC/HDPE 
      ternary blends, we found that when ORC:OBC:HDPE are at a ratio of 70:15:15, 
      cocrystallization is achieved. Although HDPE improves the compatibility of ORC 
      and OBC, the three-phase structure of the ternary blends can be observed through 
      SAXS when HDPE and OBC exceed 30 wt%. Blending HDPE and OBC (</=30 wt%) could 
      improve the mechanical property of ORC.
