Inorganic particulate compositions containing inorganic particles associated with a copolymer of a hydrophilic monomer and a hydrophobic monomer associated with the inorganic particles are provided. The particulate composition satisfies at least one of the following properties:a BET surface area of the inorganic particles is greater than 8 m2/g,a Hegman value of the inorganic particles is 75 microns or less, anda rate of water loss from the composition upon drying from a moisture level greater than 2% wt % is at least 30% greater than a composition having a corresponding content of a polyacrylate polymer associated with the particles. A method to prepare the composition and formulations for inks, paints, coatings and filled polymeric articles containing the inorganic particulate composition are also provided.
