  • Publication number: 20130116399
    Abstract: A method for carrying out polymerization processes, includes a first step involving polymerization or co-polymerization of a monomer or monomers, and a second step involving a separation step. In an embodiment, before the separation step, during the separation step, or both before and during the separation step, one or more substance is added to the reaction mixture that induces stripping, influencing of the temperature, or both stripping and influencing of the temperature such that the reaction equilibrium is shifted to the polymers and the rate of reaction to the monomer is slowed. In embodiments, before and/or in the second step, a substance is added to the reaction mixture so that a stop is achieved, and as a further function stripping and/or influencing of temperature occurs.

  • Patent number: 7762712
    Abstract: A method for the continuous phase conversion of a product in a kneader mixer, into which the product is introduced, said mixer comprising kneading elements that are mounted on at least one shaft.
