초록

새로운 스타폴리머인 바이오폴리부타디엔은 리빙 음이온중합이라는 고분자의 정밀 합성법을 통하여 분자량, 분자량분포, 조성 및 세부구조를 제어하였다. 리빙 음이온중합에 의해 n-BuLi으로 개시된 polybutadienyllithium(PBDLi)의 연쇄말단이 ESO(Epoxidized Soybean Oil)의 기능성 그룹과 커플링 반응을 일으키며 스타폴리머를 합성한다. 분자량이 1,000/5,000/10,000(g/mol)인 PBDLi을 중합하여 THF존재하에서 반응 후 GPC에 의한 분자량 및 arms분석과 $^1H$-NMR, FT-IR에 의한 고분자 구조 분석을 통하여 바이오폴리부타디엔의 합성을 확인하였다.

Novel bio-polybutadiene polymers with controlled molecular weight (MW), MW distribution, chemical composition and micro structure were synthesized by a living anionic polymerization of butadiene and the subsequent coupling reaction of the thus obtained living polybutadiene and a vegetable oil. Anionic polymerization of butadiene was carried out in THF solvent using n-BuLi initiator. The resulting living polybutadienyllithium polymer was then reacted with epoxidized soybean oil (ESO) to obtain a star-polymer of polybutadiene and vegitable oil. Three different bio-elastomers were prepared by coupling living polybutadienes of MWs 1000, 5000 and 1000g/mol with ESO. The molecular structure and MW of the polybutadienes and bioelastomers were characterized by $^1H$-NMR, FTIR and GPC techniques.
