AB  - Polyurethane (PU) is a very popular polymer that is used in a variety of 
      applications due to its good mechanical, thermal, and chemical properties. 
      However, PU recycling has received significant attention due to environmental 
      issues. In this study, we developed a recycling method for waste PU that utilizes 
      the radiation grafting technique. Grafting of waste PU was carried out using a 
      radiation technique with polyethylene-graft-maleic anhydride (PE-g-MA). The 
      PE-g-MA-grafted PU/high density polyethylene (HDPE) composite was prepared by 
      melt-blending at various concentrations (0-10 phr) of PE-g-MA-grafted PU. The 
      composites were characterized using fourier transform infrared spectroscopy 
      (FT-IR), and their surface morphology and thermal/mechanical properties are 
      reported. For 1 phr PU, the PU could be easily introduced to the HDPE during the 
      melt processing in the blender after the radiation-induced grafting of PU with 
      PE-g-MA. PE-g-MA was easily reacted with PU according to the increasing radiation 
      dose and was located at the interface between the PU and the HDPE during the melt 
      processing in the blender, which improved the interfacial interactions and the 
      mechanical properties of the resultant composites. However, the elongation at 
      break for a PU content >2 phr was drastically decreased.
