Solid organic polymers, for example, rubber and plastic particles, which may include coated papers, to especially include as recovered from recycle streams, can be made to have a sulfonated outer layer by treatment with a reactant gas containing sulfur trioxide. A silo apparatus can be employed to make these sulfonated particles, wherein untreated particles fall through the silo which is provided with a reactant gas supply. The sulfonated particles may optionally be neutralized, for example, with moist ammonia. These sulfonated particles can be used in articles of manufacture such as aggregates in cements, organic resins, cellulosics, and so forth, with beneficial properties being imparted to the composite. When used in a Portland cement, for example, increased performance concrete can result. Also, sulfonated sheets may be correspondingly employed for the sulfonated particles.

[ We claim:] [1.] 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, whereinthe 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; andthe 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; at least a portion of which matrix is embedded skin sulfonated particles having a surface layer and an interior, wherein the surface layer of the particles is sulfonated and the interior of the 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, of a discrete, solid, organic matter containing, polymeric substance, provided that if said particles are of plastic, a substantial amount of the skin sulfonated plastic particles are at least about 0.1 inch in general cross sectional distance in two dimensions, and at least about about 0.003 inch in thickness.
