Abstract
A mixed catalyst for the low pressure polymerization of 1-olefines is prepared by reacting a chromium-III compound containing water of crystallization with a metal alcoholate and by mixing the obtained chromium complex with an activator. The catalyst excels by allowing a simple preparation method and by a very good activity.
