Проведено сравнение марок СВМПЭ 510 и 517, синтезированных в Институте катализа им. Г.К. Борескова СО РАН, и GUR марок 4022, 4130 и 4150 фирмы «Celanese» (Германия и Китай). Порошки перерабатывались по технологии горячего прессования в вулканизационном прессе в соответствии с ГОСТ 16337-77 с получением образцов для исследований. Изучение структуры полимеров проведено методами рентгеноструктурного анализа и сканирующей электронной микроскопии. Результаты исследования морфологии порошков свидетельствуют, что порошки СВМПЭ состоят из кластеров более мелких субчастиц, связанных между собой фибриллами полимера. В то же время надмолекулярная структура СВМПЭ характеризуется формированием сферолитов, размеры которых уменьшаются с увеличением молекулярной массы. Рентгенограммы СВМПЭ показывают, что с увеличением молекулярной массы формируется более дефектная структура. Данное явление подтверждается методом дифференциально-сканирующей калориметрии. Выявлено уменьшение значений энтальпии плавления и степени кристалличности с увеличением молекулярной массы. Установлено, что значения степени кристалличности и плотности у СВМПЭ марки 517 российского производства сопоставимы с иностранными марками. При этом по физико-механическим и трибологическим параметрам данная марка не уступает иностранным аналогам: зарегистрированы повышение прочности при растяжении, которое достигает 45 МПа, и низкое значение скорости массового изнашивания, равное 0,07 мг/ч.</p></abstract><trans-abstract xml:lang="en"><p>This paper presents the results of a study of the properties and structure of ultra-high molecular weight polyethylene (UHMWPE) depending on grades and molecular weight. We compared the grades of UHMWPE 510 and 517 synthesized in the Federal Research Center Boreskov Institute of Catalysis, and GUR grades 4022, 4130 and 4150 from Celanese (Germany and China). Powders were processed according to the technology of hot pressing in a vulcanizing press in accordance with GOST 16337-77 to obtain samples for research. The structure of the polymers was studied by X-ray diffraction analysis and scanning electron microscopy. The study of powder morphology indicates that UHMWPE powders consist of clusters of smaller subparticles interconnected by polymer fibrils. At the same time, the supramolecular structure of UHMWPE is characterized by the formation of spherulites, the size of which decreases with increasing molecular weight. X-ray patterns of UHMWPE show that with increasing molecular weight, a more defective structure is formed. This phenomenon is confirmed by the method of differential scanning calorimetry, a decrease in the values of the enthalpy of melting and the degree of crystallinity with increasing molecular weight was revealed. We established that the value of the degree of crystallinity and density of Russian-made brand 517 is comparable to foreign brands. In terms of physical, mechanical and tribological parameters, this brand is not inferior to foreign analogues, since it has a high tensile strength, which reaches up to 45 MPa, and a low mass wear rate of 0.07 mg/h.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>полимерный материал</kwd><kwd>сверхвысокомолекулярный полиэтилен</kwd><kwd>износостойкость</kwd><kwd>прочность</kwd></kwd-group><kwd-group xml:lang="en"><kwd>polymer material</kwd><kwd>ultra-high molecular weight polyethylene</kwd><kwd>wear resistance</kwd><kwd>strength</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена при финансовой поддержке Министерства науки и высшего образования РФ, НИР № FSRG–2020–0017.
