Abstract

This study is related to the investigation of the direct incorporation of $CO_2$ to polymer using quaternary ammonium salt catalysts. Quaternary ammonium salts showed good catalytic activity of $CO_2$ fixation in the synthesis of poly[(1,3-dioxolane-2-oxo-4-yl)methyl methacrylate] [poly(DOMA)] by the direct incorporation of $CO_2$ to poly(glycidyl methacrylate)[poly(GMA)]. Among the salts tested, the ones with higher alkyl chain length and with more nucleophilic counter anion showed higher catalytic activity. The yield of carbon dioxide addition increased with the reaction temperature. Kinetic study was carried out by measuring the variation of $CO_2$, pressure in a high pressure batch reactor. The reaction rate was first order to the concentration of poly(GMA) and $CO_2$, respectively. The rate constant was $0.69L/mol{\cdot}h$ and Henry's constant of $CO_2$ in DMSO at $80^{\circ}C$ was $6.8{\times}10^{-4}mol/L{\cdot}KPa$.

4차 암모늄염 촉매 존재하에서 poly(glycidyl methacrylate)[poly(GMA)]에 이산화탄소를 직접 부가시켜 poly[(1,3-dioxolane-2-oxo-4-yl)methyl methacrylate][poly(DOMA)]를 합성하였다. 4차 암모늄염 촉매는 높은 이산화탄소 고정화 효율을 나타내었으며, 양이온의 크기가 클수록, 짝음이온의 친핵성이 강할수록 높은 촉매 활성을 나타내었다. 또한 반응온도가 높을수록 높은 이산화탄소 부가율을 나타내었다. 한편 고압 회분 반응기에서 이산화탄소의 압력변화를 관찰함으로써 실시한 속도론적 고찰 결과 반응속도는 poly(GMA)와 이산화탄소의 농도에 대하여 각각 1차 반응이었고, 이때 반응속도상수 k는 $0.69L/mol{\cdot}h$이었다. DMSO를 용매로 사용한 경우 $80^{\circ}C$에서의 $CO_2$의 Henry 상수 H'는 $6.8{\times}10^{-4}mol/L{\cdot}KPa$로 나타났다.
