    Abstract: PROBLEM TO BE SOLVED: To prepare solid preparations where a high molecular weight polymeric binder can be employed and the delayed release of an active ingredient is made possible by producing a plastic mixture of a specific polymeric binder, medicament active principle or the like under a specific condition and by molding the mixture so as to have a necessary dosage form. SOLUTION: The objective preparations are prepared by producing a plastic mixture of at least one kind selected from pharmaceutically acceptable polymeric binders having >75 K value (preferably homopolymer or a copolymer from vinylpyrrolidone) and at least one kind selected from medicament active principles, (e.g. ibuprofen or the like) and, optionally, a customary adjuvant under the condition of temperature (preferably

    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.
