Abstract

Изобретение относится к способу получения полиолефинов в петлевом реакторе путем введения препятствующего обрастанию агента через рукав, охватывающий по меньшей мере часть вала насоса. Изобретение также относится к применению препятствующего обрастанию агента для предотвращения или снижения обрастания путем подачи препятствующего обрастанию агента к импеллеру насоса при введении в петлевой реактор.
