Synthesis of Biodegradable Polymers with Carbon Dioixde
이산화탄소를 이용한 생분해성 고분자의 합성
- Published : 2004.12.01
Abstract
Biodegradation of poly(ethylene carbonate) (PEC) and their terpolymers has been investigated in vitro. PEC has been synthesized with ethylene oxide (EO) and carbon dioxide, which is one of the greenhouse gases using Zinc glutarate has been used as catalyst Carbonate terpolymers have been prepared by the use of EO, cyclohexene oxide(CHO), and carbon dioxide. High biodegradability of PEC and terpolymers with EO. has been observed. Very low biodegradation of poly(propylene carbonate) (PPC) and poly(cyclohexene carbonate) (PCHC) has been shown. The weight loss, FT-IR and SEM have been employed to characterize biodegradability.
Poly(ethylene carbonate)(PEC)와 유사한 카보네이트 삼원공중합체의 생분해성이 시험관(in vitro)에서 연구 되었다. PEC는 온실가스 가운데 하나인 이산화 탄소와 ethylene oxide(EO)를 zinc glutarate 촉매로 이용하여 합성되었고, 삼원공중합체는 EO, cyclohexene oxide(CHO)와 이산화 탄소로 만들었다. PEC와 EO를 포함하는 삼원공중합체는 생분해성을 보였으나 poly(propylene carbonate)(PPC)와 poly(cyclohexene carbonate)(PCHC)는 거의 분해되지 않았다. 생분해성은 무게 감소, FT-IR, SEM 등으로 확인하였다.
