AB  - A method for producing nanocomposites of unsaturated polyester resins (UPR) based 
      on recycled polyethylene terephthalate (PET) as a matrix has been proposed. The 
      upcycling method involves three successive stages: (1) oligoesters synthesis, (2) 
      simultaneous glycolysis and interchain exchange of oligoesters with PET, (3) 
      interaction of the obtained resins with glycol and maleic anhydride. UPRs were 
      characterized by FTIR spectroscopy and gel permeation chromatography. The 
      mechanical properties of nanocomposites obtained on the basis of these resins and 
      titanium dioxide have been investigated. It has been shown that 1,2-propylene 
      glycol units, despite their lower reactivity, significantly improve the 
      properties of UPR. The most promising nanocomposite sample exhibited tensile 
      strength 112.62 MPa, elongation at break 157.94%, and Young's modulus 29.95 MPa. 
      These results indicate that the proposed method made it possible to obtain 
      nanocomposites with high mechanical properties based on recycled PET thus 
      allowing one to create a valuable product from waste.
