When m-phenylenediamine (MPD) or m-aminophenol (MAP) was treated with formaldehyde(F), under $N_2$ stream, at the temperature $-5sim0^{circ}C$, addition condensation occurred and insoluble resins formed immediately. Under the same reaction conditions m-phenylenediamine, m-aminophenol and formaldehyde also easily copolycondensed and insoluble MPD-MAP-F type copolymer formed. MPD-MAP-F type copolycondensed resin was superior in both heat-resistant property and adsorptivity of Bromophenol Blue or Methylene Blue than the MPD-F and MAP-F type resins. From the result of TGA, under $N_2$stream, MPD-MAP-F resin showed about $40\%$ weight loss at $800^{circ}C$, and this type of resin 1g adsorbed 308mg of Bromophenol Blue.
