Параметры зависящих от микроструктуры переходов (стеклование) характеризуют поведение олигомера в аномальных низкотемпературных условиях. В работе представлены результаты исследования микроструктуры низкомолекулярных каучуков. Определяли содержание цис-1,4- и транс-1,4-структурных звеньев полидивинилизопренуретанэпоксидного олигомера. С помощью ЯМР- и ИК-спектроскопии проанализирована структура полибутадиена НТРВ-IV с концевыми гидроксильными группами, проведен сравнительный анализ микроструктуры полидивинилизопренуретанэпоксидного олигомера и низкомолекулярных каучуков с известным содержанием структурных звеньев. Полученные результаты могут быть использованы при получении олигомеров с необходимыми физико-химическими и механическими свойствами.</p></abstract><trans-abstract xml:lang="en"><p>The oligomer microstructure, reflecting the configuration of the elementary units (cis-1,4-, trans-1,4-, and 1,2-) and their distribution order in the polymer chain, decisively affects the physicochemical and rheological properties of the oligomer. Parameters of microstructure-dependent transitions (glass transition) characterize the oligomer behavior under abnormal low-temperature conditions. We present the results of studying the microstructure of low-molecular rubbers. We determined the content of cis-1,4- and trans-1,4-structural links of poly-divinyl-isoprene-urethane-epoxy oligomer. The structure of polybutadiene HTPB-IV with terminal hydroxyl groups was analyzed using NMR and IR spectroscopy. A comparative analysis of the microstructure of the poly-divinyl-isoprene-urethane-epoxy oligomer and low molecular rubbers with a known content of structural units has been carried out. The obtained results can be used to obtain oligomers with the desired physicochemical and mechanical properties.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>олигомер</kwd><kwd>микроструктура</kwd><kwd>ИК-спектроскопия</kwd><kwd>спектроскопия ЯМР</kwd><kwd>изомерия</kwd><kwd>цис-1</kwd><kwd>4-структура</kwd><kwd>транс-1</kwd><kwd>4-структура</kwd><kwd>температура стеклования</kwd></kwd-group><kwd-group xml:lang="en"><kwd>oligomer</kwd><kwd>microstructure</kwd><kwd>IR spectroscopy</kwd><kwd>nuclear magnetic resonance spectroscopy</kwd><kwd>isomerism</kwd><kwd>cis-1</kwd><kwd>4-structure</kwd><kwd>trans-1</kwd><kwd>4-structure</kwd><kwd>glass transition temperature</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">Твердов А.
