Abstract

Смеси различных полиолефинов могут быть получены прямой, предпочтительно одновременной, полимеризацией одного или нескольких полимеризуемых олефинов с применением активных каталитических систем полимеризации, содержащих два или несколько переходных металлов, по меньшей мере, один из которых включает кобальт или железо, образующие комплексные соединения с выбранными лигандами. Полиолефиновые продукты могут иметь полимеры, которые отличаются молекулярной массой, молекулярно-массовым распределением, кристалличностью или другими свойствами, и являются пригодными в качестве смол для формования и для пленок.Международная заявка была опубликована вместе с отчетом о международном поиске.
