Анализируемые материалы получены смешением в расплаве в двухшнековом реакторе-смесителе с односторонним вращением шнеков. Показано, что при концентрации ПЭТ-Г в смеси ≥70 мас. % кристаллизация ПЭТ при добавлении УЦ полностью подавляется. По данным релаксационной спектрометрии ПЭТ и ПЭТ-Г совместимы при их смешении в расплаве. </p></abstract><trans-abstract xml:lang="en"><p>The present article studies the structural features of relaxation, mechanical and rheological properties of blends of crystallizing PET and amorphous PET-G containing 0.9 wt. % of a diisocyanate chain extender (CE). The analyzed materials were obtained by melt mixing in a twin-screw reactor-mixer with one-sided rotation of screws. It was shown that at a concentration of PET-G in a blend of ≥70 wt. % by weight, the crystallization of PET added with CE is completely suppressed. According to relaxation spectrometry, PET and PET-G are compatible when they are mixed in melt. </p></trans-abstract><kwd-group xml:lang="ru"><kwd>полиэтилентерефталат</kwd><kwd>смесь полиэфиров</kwd><kwd>удлинитель цепи</kwd></kwd-group><kwd-group xml:lang="en"><kwd>polyethylene terephthalate</kwd><kwd>polyesters blend</kwd><kwd>chain extender</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">Pesetskii, S.
