ABSTRACT:
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.
