  • Patent number: 4482676
    Abstract: Vulcanizable, elastomeric chloroprene/sulfur copolymers having viscosities of from 60 to 35 ME, strengths of greater than 20 MPa and sulfur contents of from about 0.3 to 0.45% by weight are obtained by polymerizing chloroprene in the presence of from 0.05 to 0.40% by weight of sulfur to form a latex I, polymerizing chloroprene in the presence of from 0.5 to 1.5% by weight of sulfur to form a latex II, mixing latices I and II, optionally together with other sulfur-modified polychloroprene latices, in a ratio of from 4:1 to 1:4 (based in each case on solids) and peptizing the mixture, followed by working up to form the solid rubber, the percentages quoted being based on the quantity of monomer.
    Type: Grant
    Filed: March 9, 1983
    Date of Patent: November 13, 1984
    Assignee: Bayer Aktiengesellschaft
    Inventors: Rudiger Musch, Wilhelm Gobel, Eberhard Muller, Wolfgang Konter
  • Patent number: 4452947
    Abstract: Vulcanisable, elastomeric chloroprene-sulphur copolymers having viscosities of from 60 to 35 MU, strengths of >20 MPa and sulphur contents of from about 0.5 to 0.7%, by weight, in the batch are obtained by polymerising chloroprene in the presence of from 0.10 to 0.35%, by weight, of sulphur to form a latex I, polymerising chloroprene in the presence of from 0.50 to 1.00% by weight, of sulphur to form a latex II, mixing latices I and II in a ratio of from 4:1 to 1:4 (based in each case on solids), optionally together with other sulphur-modified polychloroprene latices, the mixture is peptised and worked-up to form the solid rubber, the percentages quoted being based on the quantity of monomer.
    Type: Grant
    Filed: May 20, 1983
    Date of Patent: June 5, 1984
    Assignee: Bayer Aktiengesellschaft
    Inventors: Rudiger Musch, Wilhelm Gobel, Eberhard Muller, Wolfgang Konter
  • Patent number: 4009135
    Abstract: The properties of mortar and concrete are improved by the addition to the fresh mortar or concrete of an aqueous dispersion of a plastic obtained by the emulsion polymerization of olefinically unsaturated monomers, and of a polycondensate of formaldehyde and an amino-s-triazine modified with sulfite or sulfonic acid. A well-balanced relation between the compressive strength, the tensile strength in bending, and the adhesion to aged and hardened mortar or concrete is thus obtained.

    Assignee: Hoechst Aktiengesellschaft
    Inventors: Albrecht Harreus, Eberhard Muller, Gerhart Schultz
  • Patent number: 3935177
