AB  - In this work, recycled poly(ethylene terephthalate) (PETR) was blended with 
      virgin high-density polyethylene (HDPE) in an internal mixer in an attempt to 
      obtain a material with improved properties. A compatibilizer (PE-g-MA) and a 
      chain extender (Joncryl) were added to the PETR/HDPE blend and the rheological 
      and thermal properties of the modified and unmodified blends as well as those of 
      virgin PET with virgin HDPE (PETV/HDPE). All the blends were characterized by 
      torque rheometry, differential scanning calorimetry (DSC) and thermogravimetric 
      analysis (TGA). The data obtained indicate that the incorporation of either the 
      chain extender or the compatibilizer agent led to increases in torque (and hence 
      in viscosity) of the blend compared to that of the neat polymers. The joint 
      incorporation of the chain extender and compatibilizer further increased the 
      viscosity of the systems. Their effect on the crystallinity parameters of HDPE 
      was minimal, but they reduced the crystallinity and crystallization temperature 
      of virgin and recycled PET in the blends. The thermal stability of the PETR/HDPE 
      blend was similar to that of the PETV/HDPE blend, and it was not affected by the 
      incorporation of the chain extender and/or compatibilizer.
