Joachim Holle has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Flexible foaming process for producing thermally insulated articles
    Patent number: 11772309
    Abstract: A flexible discontinuous process produces a series of at least two articles containing thermally insulating polyurethane foam from at least three streams (A), (B) and (C). The process involves mixing the at least three streams with different mixing ratios and injecting the mixture into cavities of the articles. A production unit can be used for performing this process.
    Type: Grant

    Date of Patent: October 3, 2023
    Assignee: BASF SE
    Inventors: Hendrik Wagner, Marko Grever, Joachim Holle, Joerg Krogmann

  • Method of producing suspension polymers and improved suspension polymers
    Patent number: 5142008
    Abstract: In the suspension polymerization of (meth)acrylic acid esters or of vinyl aromatics or of mixtures of such monomers, the formation of undesired, very fine "emulsion polymer", which reduces the yield, is reduced if the polymerization is carried out in the presence of polyvalent phosphonic acids or their alkali metal salts or ammonium salts or of alkali metal salts or ammonium salts of condensed inorganic phosphates, e.g. of Graham's salt.

  • Process for the production of suspension polymerizates
    Patent number: 4677173
    Abstract: The suspension polymerization of acrylic acid esters, methacrylic acid esters and vinyl aromatics alone or in admixture with subordinate amounts of other monomers is carried out in the presence of an acrylic or methacrylic acid homo or polymerizate or its alkali metal or ammonium salts as dispersing agent with the addition of an acid ester of phosphoric acid with an alkanol having 1 to 8 carbon atoms. The size of polymerizate beads produced is influenced by this procedure.
