Исследуемые материалы получали методом реакционного смешения компонентов в расплаве в экструзионном реакторе-смесителе. Показано, что для смесей ПА66/фПО характерны более существенные изменения анализируемых характеристик по сравнению с таковыми на основе ПА6 при варьировании концентрации привитого мономера. Установлено аномально резкое повышение (более чем на два десятичных порядка) вязкости расплава смеси ПА66 с фПО, содержащем 0,77 мас. % привитого мономера, по сравнению с вязкостью исходного ПА66, что обусловлено спецификой межфазных взаимодействий в смесях.</p></abstract><trans-abstract xml:lang="en"><p>The effect of addition of functionalized polyolefins (fPO) in an amount of 28 wt. % – mixtures of polyethylene and copolymer of ethylene with higher olefin containing 0.43 and 0.77 wt. % grafted monomer having two carboxyl groups in its composition – to aliphatic polyamides PA6 and PA66 on the structural features, the rheological behavior of melts and the mechanical properties of mixed materials was investigated. The materials studied were prepared by reactive mixing of the components in a melt in an extrusion reactor. It is shown that mixtures of PA66/fPO are characterized by more significant changes in the characteristics under analysis compared with those based on PA6 when the concentration of a grafted monomer is varied. An abnormally sharp increase (by more than two decimal orders) of the melt viscosity of a mixture of PA66 with fPO containing 0.77 wt. % of the grafted monomer, compared with the viscosity of initial PA66, is due to the specificity of the interphase interactions in the mixtures.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>алифатический полиамид</kwd><kwd>полиолефин</kwd><kwd>смеси полиамидов с полиолефинами</kwd><kwd>фунционализация полиолефинов</kwd><kwd>межфазные взаимодействия</kwd></kwd-group><kwd-group xml:lang="en"><kwd>aliphatic polyamides</kwd><kwd>polyolefins</kwd><kwd>mixtures of polyamides with polyolefins</kwd><kwd>functionalization of polyolefins</kwd><kwd>interphase interactions</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">Полимерные смеси / под ред.
