Abstract: The presently disclosed and/or claimed inventive concept(s) relates generally to oligomeric reaction products formed by the depolymerization of polyethylene terephthalate polymers and methods thereof. More specifically, the presently disclosed and/or claimed inventive concept(s) relates to oligomeric reaction products formed by the depolymerization of polyethylene terephthalate polymer obtained from, for example but not by way of limitation, waste products, such as beverage containers made from polyethylene terephthalate (PET). The oligomeric reaction products can, in one embodiment, be used as a starting material for polyurethanes. The presently disclosed and/or claimed inventive concept(s) also relates to processes for producing oligomeric reaction products from the depolymerization of polyethylene terephthalate.
