Показано, что реологические характеристики изученных марок существенно различаются по величине эффективной вязкости и характеру течения их расплавов при воздействии сдвиговых нагрузок. Проведено сравнение характеристик пленок, изготовленных из изученных материалов при одинаковых условиях. Стойкость пленок к раздиру неоднозначно связана со структурой ЛПЭНП. Более высокие значения сопротивления раздиру имеют пленки из ЛПЭНП с бутеновым сомономером. Пленки из ЛПЭНП с бутеновым сомономером имеют более низкие значения прочности при разрыве, чем пленки из ЛПЭНП с гексеновым сомономером. Существенное влияние на свойства пленок оказывают процессы ориентация при их получении.</p></abstract><trans-abstract xml:lang="en"><p>The rheological and mechanical properties of several LLDPE film grades with different structures were studied. It was shown that the rheological properties of the studied grades differ significantly in terms of effective viscosity and melt flow patterns under shear loads. The properties of films produced from the studied materials under identical conditions were compared. Film tear resistance is ambiguously related to the LLDPE structure. Films made from butene-containing LLDPE exhibit higher tear resistance values. Films made from butene-containing LLDPE have lower tensile strength values than films made from hexene-containing LLDPE. Orientation processes during film production significantly affect the film properties.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>линейный полиэтилен низкой плотности</kwd><kwd>эффективная вязкость расплава</kwd><kwd>прочность при разрыве</kwd><kwd>сопротивление раздиру</kwd></kwd-group><kwd-group xml:lang="en"><kwd>linear low-density polyethylene</kwd><kwd>effective viscosity</kwd><kwd>tensile strength</kwd><kwd>tear resistance</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">Шерышев М.А.
