    Type: Grant
    Filed: February 27, 1978
    Date of Patent: February 6, 1979
    Assignee: BASF Aktiengesellschaft

  • Manufacture of fibrids of polyolefins
    Patent number: 4112029
    Abstract: Fibrids of polyolefins showing a high degree of fibrillation and a high specific surface area are obtained by flashing a pressurized solution or polyolefin in pentane or in a pentane-containing solvent by passing said solution through an orifice into a space which is at a lower pressure and in which shearing forces are applied to said solution. The fibrids directly obtained may be used, for example, for the manufacture of paper or for the manufacture of textile-like webs.
    Type: Grant
    Filed: December 13, 1974
    Date of Patent: September 5, 1978
    Assignee: BASF Aktiengesellschaft
    Inventors: Bruno Sander, Eckhard Bonitz, Kurt Scherling
  • Manufacture of fibrids of polyolefins
    Patent number: 4110385
    Abstract: Fibrids of polyolefins showing a high degree of fibrillation and a high specific surface area are obtained by flashing a pressurized solution of polyolefin in pentane or in a pentane-containing solvent mixture at a temperature above the boiling point of the solvent by passing said solution through an orifice into a space which is at a lower pressure and in which shearing forces are applied to said solution. The fibrids directly obtained may be used, for example, for the manufacture of paper or for the manufacture of textile-like webs.
    Type: Grant
    Filed: August 16, 1976
    Date of Patent: August 29, 1978
    Assignee: BASF Aktiengesellschaft
    Inventors: Bruno Sander, Eckhard Bonitz, Kurt Scherling
  • Utilization of constituents of effluent from the manufacture of styrene bead polymers in the manufacture of fibrids
    Patent number: 4104341
    Abstract: A process for the manufacture of fibrids by dissolving, in a solvent, macromolecular waste materials from the bead polymerization of styrenes, and introducing the solution into a precipitation medium under the action of shearing forces to form fibrids.
    Type: Grant
    Filed: April 6, 1976
    Date of Patent: August 1, 1978
    Assignee: BASF Aktiengesellschaft
    Inventors: Hans Georg Keppler, Bruno Sander, Rolf Moeller, Eckhard Bonitz, Werner Simmler
  • Production of non-foaming aqueous suspensions of polyethylene or polypropylene fibrids
    Patent number: 4001157
    Abstract: Aqueous suspensions of polyolefin fibrids are prepared. To avoid foam formation and improve fiber-bonding, small amounts of anionic agents are added to the suspensions. The suspensions are suitable for the manufacture of paper-like or textile-like web structures distinguished by very good fiber bonding and good initial wet strength.
    Type: Grant
    Filed: November 19, 1975
    Date of Patent: January 4, 1977
    Assignee: BASF Aktiengesellschaft
    Inventors: Bruno Sander, Eckhard Bonitz, Heinz Berbner, Manfred Hoffmann
  • Vulcanized molding compositions based on bitumen and olefin polymers
    Patent number: 3992340
    Abstract: Vulcanized compositions of matter obtained by heating a mixture of bitumen, an olefin polymer, sulfur and a sulfur-containing vulcanization accelerator to a temperature of 80.degree. to 250.degree. C.
