Abstract (en)
[origin: WO2005054133A1] The invention relates to deagglomerated barium sulfate that has a primary particle size of less than 0.5 mu m and that is coated with a dispersant. The dispersant preferably has reactive groups that can interact with the surface of the barium sulfate. Particularly preferred are dispersants that provide the barium sulfate with a hydrophilic surface and that have reactive groups for coupling to or into polymers. The invention also relates to a synthetic premix comprising the deagglomerated, coated barium sulfate.
