Abstract (en)

[origin: WO0136083A1] An astatic device (1) for pressurized reactors and cyclones for making plastic materials in general and, in particular, for polymerizing olefines, comprises an astatic bar (2) which can be applied inside a reactor or cyclone vessel body (4) and including an inner insulating body (30), to which are coupled a plurality of pointed elements (36) capacitively coupled to a conductor (21) covered by a dielectric material (35) and housed in the insulating body, the conductor (21) projecting from the vessel body and being adapted to be coupled to a high voltage power supply.
