  • Patent number: 10920042
    Abstract: The invention relates to a method for preparing a hydrophobically modified clay, wherein the clay modifying agent corresponds to a quaternary ammonium based compound. The present invention further relates to a hydrophobically modified clay obtainable by such a method and to a suspension comprising such a clay, as well to the use of such a hydrophobically modified clay and of a suspension comprising such a hydrophobically modified clay. Furthermore, the present invention is also directed to a polymeric composition comprising a hydrophobically modified clay and/or a suspension comprising a hydrophobically modified clay.
