Однако наряду с этими достоинствами полиэфиримидам присущ важный недостаток – трудность переработки этих полимеров в изделия, обусловленная их высокими температурами размягчения и плавления. В последние десятилетия найдены способы снижения температуры стеклования путем увеличения гибкости основной полимерной цепи. Для этих целей в основную полимерную цепь вводят химические группы с более высокой степенью вращения, например, изопропилиденовые, гексафторизопропилиденовые, 1,2-дихлорэтиленовые и др. Полиэфиримид, исходными веществами для которого являются 3(4)-нитрофталевый ангидрид, м-фенилендиамин и бисфенол А, впервые выпущен фирмой General Elerctric под маркой Ultem и является на данный момент одним из лучших известных инженерных термопластов. Известны два метода получения таких полиэфиримидов: циклизация полиамидокислоты, которую получают поликонденсацией диангидрида 2,2-бис-[4-(3,4-дикарбоксифенокси)фенил]пропана и мета-фенилендиамина, и реакция полинитрозамещения 1,3-бис[N-(3-нитрофталимидо)]бензола и динатриевой соли бисфенола А. На сегодняшний день в отечественной научной литературе отсутствуют обзоры с подробным описанием известных методов получения полиэфиримидов серии Ultem. В настоящем обзоре обобщены и систематизированы известные литературные данные в области синтеза полиэфиримидов серии Ultem. Описаны способы получения растворимых термопластичных полиэфиримидов серии Ultem, приведены доступные методы синтеза исходных мономеров с указанием выходов продуктов реакции и их физических характеристик.</p></abstract><trans-abstract xml:lang="en"><p>Polyetherimides (PEIs) are a class of structural polymers with the most successful combination of such essential properties for practical applications as high heat resistance, thermal stability, ultimate tensile strength, elastic modulus, good dielectric properties, and high chemical and radiation resistance. However, along with these advantages, PEIs are compounds with high softening and melting points, which complicates their processing into products. In recent decades, specialists have found numerous ways to decrease the glass transition temperature by increasing the flexibility of the main polymer chain. To this end, functional groups with a higher degree of rotation, such as isopropylidene, hexafluoroisopropylidene, 1,2-dichloroethylene, and other substituents, are introduced into the main polymer chain. Polyetherimide, whose precursors are 3(4)-nitrophthalic anhydride, m-phenylenediamine, and bisphenol A, was first produced by General Electric under the Ultem brand name and is currently believed to be one of the best-known engineering thermoplastics. In particular, two synthetic methods can be used to obtain such polyetherimides. The first technique uses a cyclization of poly(amidocarboxylic acid), which is obtained by the polycondensation of dianhydride of 2,2-bis-[4-(3,4-dicarboxyphenoxy)phenyl]propane and m-phenylenediamine. The second technique uses the polynitro substitution of 1,3-bis[N-(3-nitrophthalimido)]benzene and the dynatrium salt of bisphenol A. To date, the Russian scientific literature lacks reviews with detailed descriptions of known methods for the preparation of Ultem series polyetherimides. The present review generalizes and systematizes the available literature data regarding the synthesis of the Ultem series PEIs. In addition, this study describes preparation methods of soluble thermoplastic polyetherimides of this series, available synthesis methods of initial monomers with reaction yields, and physical characteristics of such polymers.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>полиэфиримид</kwd><kwd>поликонденсация</kwd><kwd>полинитрозамещение</kwd><kwd>циклизация</kwd><kwd>растворимость</kwd><kwd>температура стеклования</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Polyetherimide</kwd><kwd>polycondensation</kwd><kwd>polynitro substitution</kwd><kwd>cyclization</kwd><kwd>solubility</kwd><kwd>glass transition temperature</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена при финансовой поддержке программы «Приоритет-2030» ФГБОУ ВО «ИРНИТУ» в рамках стратегического проекта «i.DIT» (Байкальский центр цифровых производственных технологий)</funding-statement><funding-statement xml:lang="en">The work was financially supported by the “Priority-2030” program of Irkutsk National Research University within the framework of the independent project “i.DIT” (Baikal Center for Digital Production Technologies)</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Бородулин А.С., Калинников А.Н., Музыка С.С., Терешков А.Г.
