      Mechanisms of Their Binary Blends.

AB  - The mixing of polymers, even structurally similar polyolefins, inevitably leads 
      to blend systems with a phase-separated morphology. Fundamentally understanding 
      the changes in mechanical properties and occurring deformation mechanisms of 
      these immiscible polymer blends, is important with respect to potential 
      mechanical recycling. This work focuses on the behavior of binary blends of 
      linear low-density polyethylene (LLDPE), low-density polyethylene (LDPE), 
      high-density polyethylene (HDPE), and polypropylene (PP) under tensile 
      deformation and their related changes in crystallinity and morphology. All of 
      these polymers plastically deform by shear yielding. When unmixed, the high 
      crystalline polyolefins HDPE and PP both exhibit a progressive necking 
      phenomenon. LDPE initiates a local neck before material failure, while LLDPE is 
      characterized by a uniform deformation as well as clear strain hardening. 
      LLDPE/LDPE and LLDPE/PP combinations both exhibit a clear-cut matrix switchover. 
      Polymer blends LLDPE/LDPE, LDPE/HDPE, and LDPE/PP show transition forms with 
      features of composing materials. Combining PP in an HDPE matrix causes a radical 
      switch to brittle behavior.
