Целью данной работы является определение оптимальных условий получения бутадиен-нитрильных каучуков, обеспечивающих повышение морозостойкости материалов на их основе при сохранении высокого уровня физико-механических и эксплуатационных свойств. В работе приведены рецепты полимеризации и условия синтеза. Было установлено, что дробное введение нитрила акриловой кислоты и регулятора молекулярной массы обеспечивают оптимальные условия получения синтетического каучука с требуемыми характеристиками. Результаты испытаний опытных образцов на химический состав и физико-механические свойства соответствуют нормам ТУ на каучуки марки СКН-СНТ. Наиболее перспективными для создания морозомаслобензостойких изделий являются каучуки и вулканизаты СКН 20СНТ. Физико-механические испытания показали, что вулканизат образца СКН 15СНТ, полученного при оптимальных условиях синтеза, имеет прочность при растяжении 22,7 МПа, относительное удлинение при разрыве 485% и коэффициент морозостойкости 0,84. Было также установлено, что вулканизат образца СКН 20СНТ, полученного при оптимальных условиях синтеза, имеет прочность при растяжении 24,0 МПа, относительное удлинение при разрыве 478%, коэффициент морозостойкости 0,61. Повышение маслобензостойкости морозостойких каучуков и вулканизатов СКН 15СНТ может быть реализовано за счёт регулируемого сшивания полимерных цепей каучука на стадии полимеризации. Продолжением данной работы станут расширенные испытания опытных образцов СКН 15СНТ и СКН 20СНТ с целью определения таких показателей, как температура стеклования, средняя молекулярная масса, молекулярно-массовое распределение, степень полидисперсности, содержание геля, композиционная однородность и др.</p></abstract><trans-abstract xml:lang="en"><p>Currently, there are high requirements for finished rubber products, in particular, for products that are operated in the Far North. The purpose of this work is to determine the optimal conditions for the production of nitrile butadiene rubbers, which provide an increase in the frost resistance of materials based on them while maintaining a high level of physical, mechanical and operational properties. The paper presents polymerization recipes and synthesis conditions. It was found that the fractional addition of acrylic acid nitrile and molecular weight regulator provide optimal conditions for obtaining synthetic rubber with the desired characteristics. The results of testing prototypes for chemical composition and physical and mechanical properties comply with the technical specifications for rubbers of the SKN-SNT brand. Rubbers and vulcanizates SKN 20SNT are the most promising for the creation of frost-oil-resistant products. Physical and mechanical tests have shown that the vulcanizate of the SKN 15SNT sample obtained under optimal synthesis conditions has a tensile strength of 22.7 MPa, an elongation at break of 485%, and a frost resistance coefficient of 0.84. It was also found that the vulcanizate of the SKN 20SNT sample, obtained under optimal synthesis conditions, has a tensile strength of 24.0 MPa, an elongation at break of 478%, and a frost resistance coefficient of 0.61. An increase in the oil and petrol resistance of frost-resistant rubbers and SKN 15SNT vulcanizates can be realized by controlled crosslinking of rubber polymer chains at the polymerization stage. The continuation of this work will be extended tests of prototypes SKN 15SNT and SKN 20SNT in order to determine such indicators as glass transition temperature, average molecular weight, molecular weight distribution, degree of polydispersity, gel content, compositional uniformity, etc.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>бутадиен-нитрильный каучук</kwd><kwd>синтез</kwd><kwd>вулканизат</kwd><kwd>физико-механические свойства</kwd><kwd>каучук</kwd></kwd-group><kwd-group xml:lang="en"><kwd>butadiene-nitrile rubber</kwd><kwd>synthesis</kwd><kwd>vulcanizate</kwd><kwd>physical and mechanical properties</kwd><kwd>rubber</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">Соколова М.Д.
