Abstract

In this work, oligoesters with terminal hydroxyl groups were obtained by directed glycolytic degradation of polyethylene terephthalate. The possibility of obtaining bifunctional reactive oligomers with an average molecular weight of 865 g mol-1 by directed glycolytic destruction via a dissolution-degradation strategy in dimethyl sulfoxide at a low concentration of ethylene glycol (32.3 mass parts per 100 mass parts of polyethylene terephthalate) was shown. This process allows us to partially solve the urgent problem of recycling post-consumer polyethylene terephthalate.
