Abstract
Phosphorus (P) containing monomers such as bis(3-aminophenyl)-methyl phosphine oxide(DAMPO), bis(3-aminophenyl)-phenyl phosphine oxide(DAPPO), bis[(3-aminophenoxy)phenyl] methyl phosphine oxide(BAMPO), and bis[(3-aminophenoxy)phenyl]phenyl phosphine oxide(BAPPO) and polymer such as poly(arylene ether phosphine oxide) was synthesized and utilized as curing agents or tougheners for epoxy resins, respectively. Poly(arylene ether sulfone), PES, was also prepared for comparison. The polymers were designed to have the molecular weight of 15000 or 20000 g/mole and amine end-groups so that they can react with epoxy groups. Flame retardancy of all epoxy samples were analyzed by TGA and only PEPO toughened samples were subjected to flame tests. The epoxy samples cured with P-containing monomers as well as toughened with PEPO exhibited excellent flame retardancy.

인을 함유하는 단량체 (bis(3-aminophenyl)-methyl phosphine oxide (DAMPO), bis(3-aminophenyl)-phenyl phosphine oxide (DAPPO), bis[(3-aminophenoxy)phenyl] methyl phosphine oxide(BAMPO) and bis[(3-aminophenoxy)phenyl]phenyl phosphine oxide (BAPPO) 및 고분자(poly(arylene ether phosphine oxide))를 합성하여 에폭시 수지의 경화제 및 강인화제로 사용하였다. 또한 poly(arylene ether sulfone)도 합성하여 비교시료로 사용하였다. 합성된 고분자는 분자량을 15000 또는 20000 g/mole로 제어하였으며, 아민 말단기를 가지도록 하여 에폭시 수지와 반응하도록 하였다. 에폭시 수지의 난연성은 일차로 TGA로 분석한 후, PEPO로 강인화된 에폭시 시편에 한하여 연소시험을 실시하였다. 인을 함유한 단량체로 경화된 에폭시 수지나 PEPO로 강인화된 수지 모두 아주 우수한 난연성을 보여주었다.
