ABSTRACT:
A wastewater-recyclable polymerization process for producing a polyaniline-based resin includes: feeding into a reactor an aniline monomer, an acid solution and an oxidizing agent to undergo polymerization so as to produce polyaniline resin particles; filtering the polyaniline resin particles from an acidic aqueous solution formed during the polymerization; neutralizing and drying the polyaniline resin particles to form a powder; recycling the acidic aqueous solution by mixing the acidic aqueous solution in the reactor with a fresh reactant feed which contains the aniline monomer, the acid solution and the oxidizing agent; and permitting the reactant feed to undergo polymerization in the presence of the recycled acidic aqueous solution at room temperature without cooling the reactor.
