UTILIZATION OF CRUDE GLYCEROL AND WASTE Poly(ethylene terephthalate) FOR PRODUCTION OF UNSATURED POLYESTER RESINS

Nikola Todorov, Ph. D.

Abstract :

<p> Two waste products – crude glycerol (CGly) and waste polyethylene terephthalate (PET) were utilized to obtain unsaturated polyester resins. PET flakes from beverage bottles were subjected to glycolysis at 210°C with CGly obtained as side product of biodiesel production. Two fractions of polyester polyols were separated from the glycolysis product – water soluble (WSF) and water insoluble (WIF). They were further used in a process of polycondensation with propylene glycol and maleic anhydride. The unsaturated polyesters obtained were mixed with styrene and solidified with a suitable system activator–accelerator. Some basic characteristics of the cured products were studied.</p>
