전이금속촉매에 의한 프로파길 벤젠술폰에이트의 중합
Polymerization of Propargyl Benzenesulfonate by Transition Metal Catalysts
초록
여러가지 전이금속촉매를 사용하여 프로파길 벤젠술폰에이트(PBS)를 중합시켜 술본에이트 기능기를 갖는 새로운 공액구조 고분자를 합성하였다. Mo-계 촉매가 W-계 촉매보다 본 중합이 더 효과적이였으며 특히 MoCl5-유기알루미늄 촉매가 매우 효과적인 것으로 밝혀 졌다. W 및 Mo 에톡사이드-EtAICI2 역시 PBS를 효과적으로 중합하였다. PdCl2와 PtCl2를 사용하여 PBS를 중합시킨 결과 높은 수율의 고분자를 합성할 수 있었다. 생성된 폴리(PBS)들은 사용한 촉매와 중합조건에 관계없이 유기용매에 용해하지 않았으며 검은색의 분말형이였다. 폴리(PBS)들의 열특성에 관해서도 연구하였다.
A new conjugated polymer containing sulfonate functional group was synthesized by the polymerization of propargyl benzenesulfonate(PBS) with various transition metal catalysts. Mo-based catalysts were more effective than W-based catalysts. Especially MoCl5-organoaluminum catalysts were very effective. W and Mo ethoxide-EtAlCl2 catalysts were also found to be very active for this polymerization. PdC12 also polymerized PBS to produce a high yield of polymer. The resulting poly(PBS) were insoulble in organic solvents regardless of catalysts used. This polymer was dark colored powder. Thermal properties of poly(PBS) were also studied.
