Title
(EN) PROCESS FOR TRANSITIONING BETWEEN INCOMPATIBLE POLYMERIZATION CATALYSTS
(RU) СПОСОБ ПЕРЕХОДА МЕЖДУ НЕСОВМЕСТИМЫМИ КАТАЛИЗАТОРАМИ ПОЛИМЕРИЗАЦИИ
Abstract
(RU)

В заявке описан способ перехода между полимеризационными каталитическими системами, которые не совместимы друг с другом. В частности, в заявке описан способ перехода от реакции полимеризации олефина с использованием традиционной каталитической системы Циглера-Натта к реакции полимеризации олефина с использованием металлоценовой каталитической системы.

Международная заявка была опубликована вместе с отчетом о международном поиске.
