초록
온실 가스 가운데 하나인 이산화탄소를 줄이기 위한 연구의 일환으로 이산화탄소와 산화 스틸렌을 원료로 하고 zinc glutarate를 촉매로 하여 poly(styrene carbonate)를 합성하였다. 여러 가지 분광학적인(FT-IR, 1H-NMR, 13C-NMR, GC-MS) 분석 결과 교대 공중합체임이 확인되었으며, MALDI법에 의하여 분자량(Mn)은 5.0 × 104이며, 유리전이온도는 88 ℃이고, 융융점은 240 ℃로 밝혀졌다. 이 고분자를 열분해하면 고리형 카보네이트인 styrene carbonate가 생성되는 것도 확인하였다.
In order to decrease carbon dioxide, one of the green house gas, poly(styrene carbonate) has been synthesized from carbon dioxide and styrene oxide with zinc glutarate as a catalyst. The polymer has been identified as an alternating copolymer by spectroscopic analysis, FT-IR, 1H-NMR, and 13C-NMR. The number average molecular weight (Mn) of the polymer is 5.0 × 104 g/mol and the glass transition temperature (Tg) is 88 ℃ and its melting point (Tm) is 240 ℃. The cyclic carbonate, styrene carbonate, has been obtained by thermal degradation of the polymer via the unzipping mechanism.
