Gas phase polymerisation process

摘要

A continuous process (I) for the polymerisation of a 2-12C is carried out in a gas phase polymerisation reactor by bringing a gaseous reaction mixture contg. olefin (II) into contact with a catalyst system (III) of the Ziegler-Natta type consisting of a solid catalyst consisting (A) at least one cpd. of a transition metal belonging to gps. IV, V or VI of the Periodic Table of elements and of a (B) cocatalyst comprising at least one organometallic cpd. of a metal belonging to gps. II or III of the Periodic Table. In (I), (II) is fed into the polymerisation reactor at a constant rate.
