Verwendung von Sorbentmittel für die Polyolefinreinigung.
摘要
Adsorbent for the purification of olefins and more particularly for the purification of polyolefins obtained by a process of polymerisation in the presence of coordination catalysts. This adsorbent comprises an alumina and at least one element chosen from the group comprising alkali and alkaline-earth metals with a concentration of this element of between 15 mmol and 100 mmol per 100 g of alumina. This adsorbent exhibits a remarkably low ability to isomerise olefins.
