Abstract: alpha-Olefins are polymerized in the gas phase at from 30 to 150° C. and a pressure of from 5 to 80 bar using a catalyst or a catalyst mixture containing as antistatic agent from 0.1 to 5% by weight of ZnO and/or anhydrous MgO, based on the total amount of the catalyst mixture, except for a process in which the catalyst mixture comprises a chromium catalyst and MgO-supported Ziegler catalyst which is modified with an alkene and with alkylaluminum hydride and also comprises free MgO and the total amount of the MgO is not less than 2% by weight of the catalyst mixture.

Abstract: The invention relates to a method for polymerizing alpha -olefins in a gaseous phase at a temperature ranging from 30 to 150 DEG C and at a pressure between 5 and 80 bars with a catalyst or a catalyst mixture which contains, as an antistatic agent, 0.1-5 wt. % ZnO and/or water-free MgO in relation to the total catalyst mixture. The inventive method excludes a method according to which the catalyst mixture contains a chrome catalyst and an MgO-based Ziegler catalyst which is modified with an alkene and alkylaluminium hydride and contains free MgO, the total MgO volume being no less than 2 wt. % of the catalyst mixture.
