摘要:

利用带活性羟基的N-取代3,4-富勒烯吡咯烷作为引发剂, 引发ε-己内酯开环聚合, 制备了一种具有新型结构的富勒烯末端封端聚己内酯, 通过核磁共振(1H NMR, 13C NMR)、红外光谱(FTIR)和基质辅助激光解吸电离飞行时间质谱(MALDI-TOF-MS)等手段对产物进行了结构表征, 并用热重(TG)分析和差示扫描量热(DSC)分析的方法进行了热学性能分析. 结果表明, 与聚己内酯相比产物热稳定性增加.

关键词: 富勒烯末端封端聚己内酯; 富勒烯衍生物引发剂; ε-己内酯; 开环聚合

Abstract:

Using N-substituted 3,4-fullero pyrrolidine with an active hydroxyl group as an initiator, polymerization of ε-caprolactone was performed via ring-opening polymerization. The product was characterized by 1H NMR, 13C NMR and MALDI-TOF MS and its thermal properties were determined by TG and DSC. The results show that a fullerene end-capped poly(ε-caprolactone) is achieved, and the product is more thermally tolerative than poly(ε-caprolactone).

Key words: Fullerene end-capped poly(ε-caprolactone); ε-Caprolactone; Ming-opening polymerization
