Описание проведено на основе обобщенного уравнения, предложенного ранее одним из авторов работы.</p><p>Уравнение учитывает вклад узлов сетки в упругость эластомеров. Это позволило описать зависимости модуля упругости от концентрации и размеров кристаллитов. Такие зависимости получены для следующих полимеров: полипропилен, полиизопрен, полибутадиен, политетрафторэтилен, полихлоропрен, полидиметилсилоксан. При одинаковых размерах кристаллитов модули упругости для разных полимеров близки друг другу, но они существенно возрастают при уменьшении объема кристаллитов</p></abstract><trans-abstract xml:lang="en"><p>An approach to the description and prediction of the elastic modulus of polymers in a rubbery state is presented. The description is based on the generalized equation proposed earlier by one of the authors of the work. The equation takes into account the contribution of cross-linked points to the elasticity of elastomers. This made it possible to describe the dependences of the elastic modulus on the concentration and size of crystallites. Such dependencies were obtained for the following polymers: polypropylene, polyisoprene, polybutadiene, polytetrafluoroethylene, polychloroprene, polydimethylsiloxane. For the same crystallite sizes, the elastic moduli for different polymers are close to each other, but they increase significantly with a decrease in the volume of crystallites.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>модули упругости</kwd><kwd>кристаллиты</kwd><kwd>эластомеры</kwd><kwd>полипропилен</kwd><kwd>полиизопрен</kwd><kwd>полибутадиен</kwd><kwd>политетрафторэтилен</kwd><kwd>полихлоропрен</kwd><kwd>полидиметилсилоксан</kwd></kwd-group><kwd-group xml:lang="en"><kwd>elastic moduli</kwd><kwd>crystallites</kwd><kwd>elastomers</kwd><kwd>polypropylene</kwd><kwd>polyisoprene</kwd><kwd>polybutadiene</kwd><kwd>polytetrafluoroethylene</kwd><kwd>polychloroprene</kwd><kwd>polydimethylsiloxane</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">A.A.
