Abstract
A new type terpolymer, poly (alkylene carbonate) has prepared from 1-butene oxide(1BO), cyclohexene oxide(CHO), and carbon dioxide with poly(zinc glutarate) as catslyst. The number average molecular weights of the terpolymer were found to be 40,000 ∼ 80,000 which are similar to those of the known poly(alkylene carbonate). Also glass transition temperatures(Tg) of the terpolymers with various mole ratio were related with the mole fraction and Tg of 1BO/CO2 and HO/CO2 copolymer by Fox equation.

일련의 새로운 삼원 공중합체인 폴리알킬렌카보네이트가 1-butene oxide(1BO), Cyclohexaneoxide(CHO), 그리고 이산화탄소로 부터 글루타린산의 아연 염을 촉매로 하여 합성되었다. 수평균 분자량은 대략 40,000∼80,000 정도로 기존의 폴리알킬렌카보네이트와 비슷하였으나 수율은 비교적 낮았다. 여러 가지 조성의 삼원 공중합체의 유리 전이 온도는 각각 공중합체의 1BO/CO2 와 GHO/CO2 의 사이에 몰분율과 연관하여 분포되고 있음을 보여주었다.

Keywords: poly (alkylene corbonate); 1-bulene oxide; cyclohexene oxide; carbon dioxide; zinc glutarate
