Модифицирование полиаминоамидов канифольно-малеиновыми аддуктами в количестве, равном количеству вторичных аминогрупп в повторяющемся звене полимера, осуществляли в расплаве при температуре 160–180 °С в течение 3 ч при непрерывном перемешивании. Протекание процесса контролировали по изменению кислотного и аминного чисел реакционной массы. Наиболее интенсивно модифицирование полиаминоамидов канифольно-малеиновыми аддуктами с различным содержанием малеопимаровой кислоты протекает в течение часа. Установлено, что в наибольшей степени с полиаминоамидами реагирует канифольномалеиновый аддукт с содержанием малеопимаровой кислоты 16,46 мас.%, при этом степень модифицирования полимера достигает 57,39 %. Структуру синтезированных продуктов изучали методом ИК-спектроскопии. Изученные физико-химические свойства (растворимость, температура размягчения, вязкость растворов, кислотное и аминное числа и др.) полученных продуктов свидетельствуют, что продукты реакций представляют собой сложные смеси, состоящие из химически модифицированных полиаминоамидов, N-замещенных имидов малеопимаровой кислоты и непрореагировавших канифольно-малеиновых аддуктов (свободные смоляные и малеопимаровая кислоты).</p></abstract><trans-abstract xml:lang="en"><p>The features of the process of chemical modification of polyaminoamides based on adipic acid and diethylenetriamine with rosin-maleic adducts differing in the content of maleopimaric acid (8.55; 16.46 and 31.12 % wt.) are considered. Modification of polyaminoamides with rosin-maleic adducts in the amount equal to the number of secondary amino groups in the repeating unit of the polymer was carried out in the melt at temperature 160–180 °C for 3 h under continuous stirring. The process was controlled by monitoring the change in the acid and amine numbers of the reaction mass. The most intensive modification of polyaminoamides by rosin-maleic adducts with different content of maleopimaric acid occurs within 1 h. It has been established that the rosin-maleic adduct with the 16.46 % wt. content of maleopimaric acid reacts with polyaminoamides and the degree of polymer modification reaches 57.39 %. The structure of the synthesized products was studied by IR-spectroscopy. The studied physicochemical properties (solubility, softening point, viscosity of solutions, acid and amine numbers, etc.) of the obtained products indicate that the reaction products are complex mixtures that consist of chemically modified polyaminoamides, N-substituted maleopimaric acid imides and unreacted rosin-maleic adducts (free resin and maleopimaric acids).</p></trans-abstract><kwd-group xml:lang="ru"><kwd>адипиновая кислота</kwd><kwd>диэтилентриамин</kwd><kwd>полиаминоамиды</kwd><kwd>канифольно-малеиновый аддукт</kwd><kwd>малеопимаровая кислота</kwd><kwd>модифицирование</kwd></kwd-group><kwd-group xml:lang="en"><kwd>adipic acid</kwd><kwd>diethylenetriamine</kwd><kwd>polyaminoamides</kwd><kwd>rosin-maleic adduct</kwd><kwd>maleopimaric acid</kwd><kwd>modification</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">Шампетье, Г.
