초록
3-Aminopropyltrimethoxysilane(1NS) 또는 N-[3-(trimethoxysilyl)propyl]ethylenediamine(2NS)으로 표면 기능화된 실리카에 1-butyl-4-methylpyridinium chloride(Cl)와 tributylmethylammonium chloride(Amm), benzyldimethyltetradecylammonium chloride(Ben), 1-butyl-1-methylpyrrolidinium chloride(Pyr)와 같은 이온성 액체를 이용하여 표면처리한 후 메탈로센 촉매를 담지하여 에틸렌 중합을 실시하였다. SiO2/1NS/IL/(n-BuCp)2ZrCl2 촉매와 SiO2/2NS/IL/(n-BuCp)2ZrCl2 촉매의 Zr 함량은 아미노실란 화합물로만 표면 처리된 촉매보다 감소하였다. SiO2/1NS/IL/(n- BuCp)2ZrCl2 촉매의 중합 활성은 SiO2/1NS/(n-BuCp)2ZrCl2 촉매보다 증가하였다. 반면, SiO2/2NS/IL/(n-BuCp)2ZrCl2은 Zr 함량의 감소로 중합 활성은 SiO2/2NS/(n-BuCp)2ZrCl2 촉매에 비해 감소하였다.
Metallocene was supported on the silica, which was functionalized with aminosilanes such as aminopropyltrimethoxysilane (1NS) or N-[3-(trimethoxysilyl)propyl]ethylenediamine (2NS), and ionic liquids such as 1-butyl-4-methylpyridinium chloride (Cl), tributylmethylammonium chloride (Amm), benzyldimethyltetradecylammonium chloride (Ben), 1-butyl-1-methylpyrrolidinium chloride (Pyr), and then ethylene polymerizations were performed. The Zr contents of SiO2/1NS/IL/(n-BuCp)2ZrCl2 and SiO2/2NS/IL/(n-BuCp)2ZrCl2 were lower than those of only aminosilane-treated silicas. However, the polymerization activity of SiO2/1NS/IL/(n-BuCp)2ZrCl2 was higher than that of SiO2/1NS/(n-BuCp)2ZrCl2. The polymerization activity of SiO2/2NS/IL/(n-BuCp)2ZrCl2 was lower than that of SiO2/2NS/(n-BuCp)2ZrCl2 due to much lower Zr content.
