AB  - The paper investigates the synthesis of eco-friendly composites and their 
      properties before and after immersion in solvents of different chemical natures. 
      For their preparation, unsaturated polyester resin (UPR) based on recycled poly 
      (ethylene terephthalate) (PET) and peanut shell powder (PSP) were used. 
      Polymerization was carried out in the presence of environmentally friendly 
      polymeric cobalt. Distilled water, acetone, 10% hydrochloric acid, 40% sodium 
      hydroxide, toluene, and 2% sodium carbonate were used as solvents in the chemical 
      resistance test. Changes in the structure, properties, and appearance 
      (morphology) of composites after 140 days of immersion in solvents were 
      investigated. The results show that both the resin and its composites show 
      resistance towards 10% HCl and toluene. The immersion in water has no significant 
      effect on the resin, but for PSP composites, the plasticizing effect of water was 
      observed. In acetone, after only one day, the resin and its composite with 10% 
      PSP shrink and fall into pieces. However, the most destructive is an alkaline 
      environment. After the immersion test, a huge increase in mass and a 
      deterioration of gloss and thermomechanical properties were observed. The 
      destructive influence of the 40% NaOH environment mainly concerned the resin.
