  • Patent number: 10253117
    Abstract: The invention describes a process for producing a diene polymer, the process including the following steps in this order i) polymerizing one or more diene monomers in the presence of a catalyst composition to give a reaction mixture; ii) adding to the reaction mixture one or more alkoxysilane compounds; iii) adding S2Cl2, SCl2, SOCl2, S2Br2, SOBr2 or a mixture thereof to the reaction mixture; and iv) optionally adding a protic agent to the reaction mixture so as to deactivate the catalyst. The invention further includes polymers that are obtainable according to this process, as well as products including the polymer.

  • Patent number: 4569228
    Abstract: A probe tube which is introduced into a reaction container for measuring the operating condition of a medium in the interior of the container has a first seal which is resistant to temperature and a second seal which is resistant to pressure and gas-tight. Those seal respectively close the inner and outer ends of the probe tube. The interior of the probe tube communications with the interior of the reaction container by way of an opening, whereby the temperature-resistant seal at the tip of the probe tube is relieved of the loading of pressure forces.
