Abstract

Настоящее изобретение относится к способу получения полиолефина в петлевом реакторе полимеризации, причем указанный петлевой реактор включает множество взаимосвязанных труб, определяющих путь течения суспензии полиолефина, и один или более осадительных стояков, предусмотренных по меньшей мере на одной горизонтальной части указанных взаимосвязанных труб, указанный способ включает стадии подачи олефинового мономера, жидкого разбавителя, катализатора полимеризации, возможно, водорода и, возможно, олефинового сомономера в указанный петлевой реактор и полимеризации указанного олефинового мономера и указанного возможного сомономера с получением указанной полиолефиновой суспензии в указанном петлевом реакторе, где скорость циркуляции полиолефиновой суспензии внутри по меньшей мере одной горизонтальной части указанных взаимосвязанных труб, снабженных одним или более осадительными стояками, понижена по меньшей мере на 20% и не более чем на 60% по сравнению со скоростью циркуляции внутри остальной части указанного петлевого реактора.
