VERFAHREN ZUR POLYMERISATION VON AETHYLEN IN GASPHASE

摘要

Ethylene is polymerized in a gaseous phase and in contact with a Ziegler/Natta type solid catalyst capable of producing polyethylene in the form of granules having an easily controllable and homogeneous granulometric size, the polymerization being conducted in a tubular reactor in which the catalyst and the polymer granules which are formed are carried along the reactor by the flow of the gas.
