<p>The invention relates to a method a device for feeding a mud-like catalyst mixture into a polymerization reactor. The catalyst mixture is fed from a container (12) into a batching space (23,24) of a feeder (10) connected thereto, from which channel the catalyst mixture is further fed by batches into the polymerization reactor by means of the pressure of a medium fed into said feeder (10). In accordance with the invention, after each catalyst batch fed into the polymerization reactor, the medium is essentially totally removed from the batching space (23,24) of the feeder (10) by leading the medium via an outlet channel (19b) into a space between two valves (26, 28) of on/off type before filling the batching space (23,24) with a new catalyst batch. The invention also relates to a device for realizing the method. <IMAGE></p> |
