Abstract	m-Phenylenediamine(MPD) 및 m-aminophenol(MAP)을 각각 질소기류중, pH1, -5∼0℃에서 포름알데히드와 반응시키면 약간의 발열과 함께 부가축합반응이 진행되어 불용성인 중합체를 생성한다. 또한 같은 반응 조건하에서 공축합반응체도 생성하며, 생성 중합체의 내열성 및 Bromophenol Blue 또는 Methylene Blue의 흡착성은 공축합중합체의 경우가 우수하다. MPD-MAP-F계(F: 포름알데히드) 공축합수지는 TGA에서 몰비 1:2:6의 경우, 800℃에서 각 40%의 중량 손실을 나타내는 좋은 내열성을 띄며, 몰비 2:1:6의 공축합수지는 1g당 Bromophenol Blue를 308mg을 흡착하는우수한 흡착성을 띈다. When m-phenylenediamine (MPD) or m-aminophenol (MAP) was treated with formaldehyde(F), under N2 stream, at the temperature -5∼0℃, 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 /sBlue or Methylene Blue than the MPD-F and MAP-F type resins. From the result of TGA, under N2stream, MPD-MAP-F resin showed about 40% weight loss at 800℃, and this type of resin 1g adsorbed 308mg of Bromophenol Blue.
