Patents by Inventor Gerd Granner

Gerd Granner 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).

  • Polymer-modified inorganic particles
    Patent number: 7196131
    Abstract: The invention relates to polymer modified inorganic particles with a layer structure with an average particle diameter of 5 nm to 20,000 nm, containing 20 to 5000 mass % interlamellarly, in relation to the anhydrous inorganic particle, of a mixture of aminoplasts and water. These polymer modified inorganic particles are produced by swelling the inorganic particles with aldehydes and then reacting the inorganic particles with multifunctional C1–C30 amino compounds. The invention also relates to plastic containing polymer modified particles with a layer structure and to semi-finished products and moulded material produced from the same.
    Type: Grant
    Filed: December 12, 2001
    Date of Patent: March 27, 2007
    Assignee: Agrolinz Melamin GmbH
    Inventors: Manfred Rätzsch, René Dicke, Markus Machherndl, Gerd Granner
  • Modified inorganic particles
    Patent number: 7012108
    Abstract: The invention relates to modified inorganic particles with a layer structure with an average particle diameter of 5 nm to 20000 nm, comprising an outer shell consisting of aminoplasts which contain, interlamellarly, multifunctional C1–C30 amino compounds of the melamine, melamine derivative, urea, urea derivative, guanidine, guanidine derivative, cyanamide, dicyandiamide, sulphonamide and/or aniline-type. The invention also relates to the production of said modified inorganic particles and to their use in thermoplastics and duroplastics.
