Skin sulfonated particles in matrices

A filled composition comprising a product prepared by curing a matrix selected from the group consisting of inorganic settable, organic resin, and cellulosic matrices, and combinations thereof, wherein

• the inorganic settable matrix is selected from the group consisting of a calcium-silicate cement, a calcium sulfate-containing cement, a phosphate-based cement, an aluminous cement, a magnesium oxy chlorite type cement, and combinations thereof;
• the organic resin matrix is selected from the group consisting of an epoxy, a urethane, a urea-formaldehyde resin, a lignin, a binder made from a water based paint or roofing composition, or an asphalt emulsion, and combinations thereof;
• and
• the cellulosic matrix is selected from the group consisting of a simple cellulosic fiber material made from a slurry, and an intractable cellulosic polymeric mass made from action of an oxidizing agent on a wet cellulosics fabrication composition;
• in at least a portion of which matrix is embedded skin sulfonated rubber particles having a surface layer and an interior, wherein the surface layer of said particles is sulfonated and the interior of said particles is essentially not sulfonated, present as an aggregate initially before any heating or pressing processing, present finally as a particle or solid residue thereof in the matrix and not in liquid solution, said particles being discrete, solid and derived from tires.
