    Abstract: The invention relates to 1,2-di-imines with at least one nitrogen-heterocyclic ligand which is bonded to at least one of the two imine nitrogen atoms by a nitrogen atom; and to a method for producing said 1,2-di-imines. The invention also relates to metal complexes of these 1,2-di-imines with transition metals of groups 8, 9 or 10 of the periodic table, to a method for producing the same and to the use of the metal complexes as catalysts in a method for polymerizing unsaturated compounds. Finally, the invention relates to a method for producing polyolefins by polymerizing unsaturated compounds in the presence of an activator and a catalyst in the form of the metal complex.

    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.
