Abstract
Polyethylene terephthalate (PET) wastes were depolymerized by diethylene glycol (DEG)‐diethanol amine (DEA) binary mixtures as a solvent system in various DEG:DEA ratios and sodium hydroxide as the trans‐esterification catalyst. The obtained product was vacuum filtered for separation and characterization of resulting phases by using spectroscopic and chromatographic techniques. Liquid phase of recyclate was an OH containing product and was used as a portion of polyol content, being compared with virgin polyol in rigid polyurethane foam formulation.
