Abstract
In this work, methods for obtaining unsaturated polyester resins based on the products of chemical recycling of post-consumer polyethylene terephthalate with various agents are compared. A process based on simultaneous glycolysis and interchain exchange of polyethylene terephthalate and oligoethylene phthalate with hydroxyl end groups has been proposed. The advantages of this process are shown, including rapid obtaining polyester resins of high molecular weight and the lesser influence of side reactions and degradation reactions. The unsaturated resin with a weight average molecular weight of 3100 g/mol was obtained.
