C NMR和GPC对聚合物结构进行表征。结果表明,PPI端氨基能够作为引发剂参与反应引发BLG-NCA开环聚合,并证实成功合成了多臂聚丙烯亚胺-聚谷氨酸苄酯聚合物。该聚合物有望成为新型的非病毒基因载体材料。
Abstract
Multi-armed polypropylenimine dendrimer-poly(benzyl-L-glutamate) was synthesized by ring-opening polymerization of BLG-NCA using primary amineterminated polypropylenimine dendrimer (PPI) as the macroinitiator. Its chemical structure was characterized by IR

and GPC analysis. The results showed that the primary amine of PPI participated in initiating the ring-opening polymerization of BLG-NCA monomer. And multiarmed polypropylenimine dendrimer-poly(benzyl-L-glutamate) was successful synthesized. The multi-armed polymer might be a potential candidate as nonviral gene carriers.
