Abstract: The invention relates to an extrusion device, particularly an extrusion device for thermoplastic or dough-like masses or highly tenacious melts, and to the use of said device. The extrusion device has a housing (11), at least one conveyor worm (12) arranged in a housing and an outlet (20) disposed on the front face of the housing (11) close to the end of each conveyor screw which is furthest away from the drive end. At least one stripping member (21) is arranged in between the end (14) of each conveyor screw (12) furthest away from the drive end and the outlet (20). The device is particularly suitable for producing granulates, preferably those containing active substances.

Abstract: The invention relates to a continuous gas phase fluidization method for producing ethylene homopolymerisates and copolymerisates with a density (d) of 0.87 to 0.97 g/cm . According to said method, ethylene or mixtures of ethylene and C3- to C8- alpha -monoolefins are (co)polymerised in the polymerisation zone of a gas phase fluidized bed reactor at pressures of 1 to 100 bar and at temperatures of 30 to 125 DEG C in the gas phase in an intermixed bed of fine particulate polymerisate in the presence of a supported chromium catalyst. The polymerisation heat produced is evacuated by cooling the reactor gas, said reactor gas being guided in a closed circuit, and the resulting (co)polymerisate is transferred out of the gas phase fluidized bed reactor. In order to produce a (co)polymerisate of a pre-selected density (d), the (co)polymerisation is carried out at a temperature within a range limited by an upper envelope of equation (I) and a lower envelope of equation (II), the variables in said equations having the following meanings: TH = the highest reaction temperature in DEG C; TN = the lowest reaction temperature in DEG C; and d'= the numerical value of the density (d) of the (co)polymerisate to be produced.

Abstract: Continuous gas phase polymerization for producing ethylene homopolymers and -copolymers, comprises polymerizing ethylene or monoolefin from but-1-en, pent-1-en, 2-methylpentene, hex-1-en, hept-1-en and oct-1-en in the a polymerization reactor; and endowing a catalyst poison with boiling point higher than a circle gas pipeline, and molecular weight greater than 100 g/mol at a position after the reactor, but before the cooler and compressor. Continuous gas phase polymerization for producing ethylene homopolymers and -copolymers, comprises polymerizing ethylene and/or monoolefin from but-1-en, pent-1-en, 2-methylpentene, hex-1-en, hept-1-en or oct-1-en, in the polymerization zone of a gas phase polymerization reactor at 30-125[deg]C and 1-100 bar in the gaseous phase in a finely divided polymer bed, in the presence of a metallocene catalyst in carrier form polymer, where a reactor gas is lead into the circle gas pipeline for the removal of the polymerization heat; and endowing a catalyst poison with boiling point higher than circle gas pipeline and molecular weight greater than 100 g/mol at a position after the reactor but before the cooler and compressor, for preventing polymer linings, such that the productivity of the catalyst is not essentially affected in the reactor.

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.
