Из них полилактид (ПЛА) рассматривается как один из наиболее перспективных биоразлагаемых пластиков. В связи с особенностями данного полимера, в частности его хрупкостью, исследователи разрабатывают полимерные композиции с добавкой пластифицирующих полимеров, таким компонентом может выступать полибутиленадипинаттерефталат (ПБАТ). После воздействия УФ-излучения с длиной волны 254 нм в течение 100 ч на смеси ПЛА/ПБАТ установлено, что за счет подверженности ПЛА УФ-излучению, разрушение материала происходит преимущественно в матрице полилактида, при этом снижаются теплофизические характеристики. На дифрактограммах образцов присутствуют рефлексы, характерные для кристаллической α-формы полилактида. После облучением ультрафиолетом интенсивность рефлексов снижается у 100ПЛА и в смеси 70ПЛА/30ПБАТ, что свидетельствует о разрушении кристаллической структуры полилактида.</p></abstract><trans-abstract xml:lang="en"><p>Currently, biodegradable polymers are playing an increasingly important role in order to improve the environmental situation. Of these, polylactide (PLA) is considered as one of the most promising biodegradable plastics. Due to the peculiarities of this polymer, in particular its fragility, researchers are developing polymer compositions with the addition of plasticizing polymers, such a component can be polybutyleneadipateterephthalate (PBAT). After exposure to UV radiation with a wavelength of 254 nm for 100 hours on a mix- ture of PLA/PBAT found that due to the susceptibility of PLA to UV radiation, the destruction of the material occurs mainly in the polylactide matrix, while the thermophysical characteristics decrease. The diffractograms of the samples show reflexes characteristic of the crystalline α-form of polylactide. After ultraviolet irradiation, the intensity of reflexes decreases in 100PLA and in a blend of 70PLA / 30PBAT, which indicates the destruc- tion of the crystal structure of the polylactide.</p></trans-abstract><kwd-group xml:lang="en"><kwd>polylactide</kwd><kwd>polybutyleneadipateterephthalate</kwd><kwd>polymer mixtures</kwd><kwd>X-ray diffraction study</kwd><kwd>photodegradation.</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">Huda M.S., Drzal L.T., Mohanty A.K., Misra M.
