Аннотация
Использование активирующих носителей в приготовлении нанесенных металлоценовых катализаторов полимеризации олефинов, получаемых реакцией мезопористого силикагеля с алюминийорганическими соединениями, термоокислительной обработкой и фторированием, позволяет избежать использования дорогостоящего и малодоступного метилалюмоксана (МАО). В работе представлены результаты исследования влияния температуры прокаливания мезопористого силикагеля ES70 на основные характеристики фторированных носителей на его основе и способность полученных носителей к активации (η5-BuC5H4)2ZrCl2 в присутствии Et3Al. Эксперименты по суспензионной сополимеризации этилена и гексена‑1 выявили более высокую активность полученных катализаторов (2,2–2,5 кгПЭ/гкат) по сравнению с наносимым металлоценовым катализатором, синтезированным с использованием МАО (1,73 кгПЭ/гкат). Показано, что повышение температуры предварительного прокаливания носителя снижает активность катализатора, практически не влияя на характеристики сополимера, что может быть использовано в полиолефиновой индустрии для управления важным параметром производительности нанесенного металлоценового катализатора полимеризации этилена.
