This work mainly introduces the recyclability of polypropylene (PP) modified by regenerated polyurethane (PU) that was obtained after partial thermochemical decomposition of waste PU. The influence of regenerated PU on the mechanical properties and thermal stability of PP during multiple processing cycles was evaluated by a universal testing machine, differential scanning calorimetry, and thermogravimetric analyses. The data showed that the mechanical properties of the modified PP were dependent on the content of regenerated PU with the increase in the number of processing cycles, whereas the thermal stability of the modified PP was almost independent of the content of regenerated PU.
