초록

몇 가지 합성한 poly(6-dialkylamino-1,3,5-triazine-2,4-dithioxylene) 유도체들은 poly(6-dialkylamino-1,3,5-triazine-2,4-dithiol과 m- 또는 p-dibromide xylene으로부터 $70^{\circ}C$에서 약 24시간 동안 cetyltrimethyl ammo-nium bromide와 중축합반응 시켜서 얻었다. 합성해서 얻은 유도체들의 굴절률이 97~196.6을 보였으며, 물흡광계수는 97~196.6범위에서 나타났다. 따라서 이들 고분자 유도체들이 높은 전자밀도를 가지는 황 원자와 트리아진 고리를 가지므로 인해 복굴절 현상이 없으면서 높은 굴절률을 가진다는 것을 알았다.

Several poly(6-dialkylamino-1,3,5-triazine-2,4-dithioxylene) derivatives were synthesized by the polycondensation of 6-dialkylamino-1,3,5-triazine-2.4-dithiol with m- and p-dibromide xylene in a cetyltrimethyl ammonium bromide at $70^{\circ}C$ for 24h. The synthesized derivatives had refractive Indexes of 1.580~1.697 and had molar absorptivity of 97~196.6. In these derivatives, we knew that they are a polymer having high refraction indexes without double refraction because they contain triazine rings and sulfur atoms with high electron density.
