초록
이산화탄소를 이용하여 여러 가지 사슬을 가진 새로운 poly(alkylene carbonate)를 합성하였다. Cyclopentene oxide, 1-Hexene oxide, 1-Dodecene oxide를 이용한 새로운 카보네이트가 비교적 높은 분자량으로 합성되어 그 유리 전이 온도를 측정하여 구조와 연관하여 비교하였다. 고리구조를 주쇄에 가질 경우 유리 전이 온도는 현저하게 증가하였고, 긴 알킬 사슬을 가진 경우 유리 전이 온도는 영하에 분포되는 것을 관찰하였다.
New poly(alkylene carbonate)s with various alkyl chain have been synthesized with carbon dioxide and cyclopentene oxide, 1-hexene oxide and 1-dodecene oxide. Their molecular weight are rather high enough to give proper mechanical properties. The glass transition temperatures of the poly(alkylene carbonate)s are correlated with their structure. Higher transition temperature was observed in case of cyclic chain, however those are lied under 0℃ in case of linear alkyl chain.
