m-Phenylenediamine (MPD) is an aromatic diamine. It copolymerizes with iso- or terephthaloyl chloride and 3 5-diaminobenzoic acid or 2 4-diaminobenzene sulfonic acid (or sulfonate) to afford copolyamides by low temperature SOLUTIONon polymerization. MPD has been reported to be formed selectively during the hydrogenation of m-dinitrobenzene in the presence of bimetallic Ni-Pt catalysts supported on carbon. Cyclic voltammetric method has been proposed to study the electrochemical copolymerization of aniline with MPD in sulfuric acid SOLUTIONon.
