Abstract
When m-phenylenediamine (MPD) or m-aminophenol (MAP) was treated with formaldehyde(F), under $N_2$ stream, at the temperature $-5\sim0^{\circ}C$, 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.
m-Phenylenediamine(MPD) 및 m-aminophenol(MAP)을 각각 질소기류중, pH1, m-Phenylenediamine(MPD) 및 m-aminophenol(MAP)을 각각 窒素氣流中, pH1, $-5{\sim}0^{\circ}C$에서 포름알데히드와 반응시키면 약간의 發熱과 함께 附加縮合反應이 진행되어 不溶性인 重合體를 生成한다. 또한 같은 反應 條件下에서 恐縮合反應體도 生成하며, 生成 重合體의 耐熱性 및 Bromophenol Blue 또는 Methylene Blue의 吸着性은 恐縮合重合體의 경우가 우수하다. MPD-MAP-F계(F: 포름알데히드) 恐縮合樹脂는 TGA에서 몰比 1:2:6의 경우, $800^{\circ}C$에서 각 $40\%$의 重量 損失을 나타내는 좋은 耐熱性을 띄며, 몰比 2:1:6의 恐縮合樹脂는 1g당 Bromophenol Blue를 308mg을 吸着하는우수한 吸着性을 띈다.
