<p>A process of chemically densifying polystyrene comprises the steps of creating a densifying system comprising at least one densifying reagent and contacting polystyrene with said densifying solution. Densified polystyrene can be reclaimed by creating a reclamation system comprising at least one solubilizing reagent, dissolving the densified polystyrene in said reclamation system, precipitating the polystyrene from the resulting solution and separating the precipitated and purified polystyrene from the solution. The products of the densification and reclamation processes can be altered by varying the reagents and solvents, and their relative concentrations. The products can include an oil, a gel, a gum, a hard, miniaturized version of the original form, or a granular or fibrous product. Paint, ink and/or contaminants can be removed from plastics by the addition of an abrasive to the densifying solution and/or reclamation solution.</p> |
