Abstract

В настоящем изобретении описан способ получения фторированного каталитически активного соединения, каталитических композиций, и способов полимеризации, включающих такое соединение. Способ получения фторированного каталитически активного соединения включает контактирование металлоценового компонента катализатора с фторированной неорганической солью, в течение времени, достаточного для получения фторированного металлоценового компонента катализатора, такого как описанный в следующем примере:
Figure 00000001
где R представляет собой замещающие группы, выбранные из группы, включающей алкилы C1-С10 в конкретном предпочтительном варианте, р представляет собой 0 или целое число от 1 до 5. Фторированную неорганическую соль в конкретном предпочтительном варианте описывают как соединение, которое генерирует фторид-ионы при контактировании с разбавителем, по крайней мере на 50 мас.% состоящем из воды. Технический результат - увеличение выхода продукта, высокая производительность фторированного каталитически активного соединения. 8 з.п.ф-лы.
