AB  - The most widely used commodity polymers in the rigid packaging industry are 
      polypropylene (PP) and high-density polyethylene (HDPE). For example, blow 
      molding grade of HDPE as a bottle and injection molding grade of PP as a cap are 
      often used to produce detergent bottles. Therefore, the recycled HDPE bottles 
      from post-consumer waste include PP as a contaminant originated from PP bottle 
      caps. To simulate mechanical recycling of bottle waste, the mechanical properties 
      of HDPE-rich-HDPE/PP virgin model blend were studied. For compatibilization, 
      ethylene-based olefin block copolymer, propylene-based olefin block copolymer, 
      ethylene propylene random copolymer, and styrene-butadiene-styrene triblock 
      copolymer were chosen as potential compatibilizer candidates. Contact angle 
      measurements, morphological analysis, adhesion tests of compatibilizer candidates 
      to polymer blend components and the tensile as well as tensile impact properties 
      of the ternary blends were studied. It was found that the ethylene-based olefin 
      block copolymer was the most effective compatibilizer resulting in a return of 
      mechanical properties to those of neat vHDPE due to its ability to encapsulate 
      dispersed vPP particles in a vHDPE matrix (core-shell morphology) and the best 
      adhesion to polymer blend components.
