    摘要: The invention relates to a method for carrying out polymerisation processes, wherein a (co-)polymerisation of monomer(s) takes place in a first stage and a separation of product and monomers, oligomers, reaction products and additives or solvents takes place in a second stage. Before and/or in the second stage, which is to say during finishing, a substance is to be added to the reaction mixture, by which substance stripping and/or influencing of the temperature is effected, whereby the reaction equilibrium is shifted toward the polymers, wherein the speed of reaction to the monomer is slowed. A second possibility is that before and/or in the second stage, which is to say during finishing, a substance is added to the reaction mixture, by which substance stopping and, as a second function stripping, and/or influencing of the temperature is effected.

    摘要: The invention relates to a method for the production of halobutyl rubber by copolymerization of isobutyl and isoprene in a solvent to form butyl rubber, wherein the solvent can be non-soluble for a suspension process (for example chloromethane) or be soluble for a solution process (for example, isopentane, pentane, hexane), and the subsequent halogenation of the butyl rubber. According to the invention, at least the halogenation should be carried out using a halogenation agent (8), in particular chlorine or bromine, in a halogenation kneader (7).
