Изучены основные характеристики полученных ненасыщенныхполиэфирных смол. В сравнении с другими показаны преимущества процесса, основанного на одновременном гликолизе и межцепном обмене полиэтилентерефталата и олигоэтиленфталата с гидроксильными концевыми группами, а именно: возможность получения полиэфирных смол с высокой молекулярной массой (Mw) 3100 г/моль и меньшее влияние побочных реакций и реакций деструкции.</p></abstract><trans-abstract xml:lang="en"><p>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.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>полиэтилентерефталат</kwd><kwd>ПЭТ</kwd><kwd>ПЭТФ</kwd><kwd>химический рециклинг</kwd><kwd>гликолиз</kwd><kwd>сложные олигоэфиры</kwd><kwd>ненасыщенные полиэфирные смолы</kwd></kwd-group><kwd-group xml:lang="en"><kwd>polyethylene terephthalate</kwd><kwd>PET</kwd><kwd>chemical recycling</kwd><kwd>glycolysis</kwd><kwd>oligoesters</kwd><kwd>unsaturated polyester resins</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Киршанов К.А., Гервальд А.Ю., Томс Р.В.
