The effects of secondary polyethylene terephthalate alcoholysis conditions on the structure and particles of hydroxyl-containing polyester polyols were investigated. The dependence of the physicochemical package of hydroxyl-containing polyester polyols on the amount in the reaction medium was established. A mixture of unsaturated polyesters based on polyethylene terephthalate alcoholysis products containing mixed waste was investigated. The structures of alcoholysis products and unsaturated polyesters based on them were investigated by IR spectroscopy. The technological package of unsaturated polyesters synthesized on the basis of alcoholysis products of secondary polyethylene terephthalate meets the technical requirements for the production of polymer composites and glass fiber pipes. The effect of hardener system on the curing process is shown. Unsaturated polyester brands “PN-Mama-02”, “PN-Mama-03A”, “PN-Mama-03” show that the polymer composite pipe products can replace the imported “Body” brand resin is showing.
