Abstract
Soluble poly(ε-lysine)s bearing β-cyclodextrin (β-CD) moieties were prepared by three amino β-CD derivatives and N-succinylated poly(ε-lysine), in which the poly(ε-lysine) and amino β-CD derivatives were bonded covalently to the end carboxyl groups of succinic acid by peptide bonds. 1-Ethyl-3-(3-dimethylaminopropyl) carbodiimide hydrochloride (EDCI) and N-hydroxysuccinimide (NHS) were chosen to assist the reaction. The three poly(ε-lysine) derivatives were characterized by 1H nuclear magnetic resonance (1H NMR) and Fourier transform infrared (FT-IR). The synthesis process is simple, feasible and has strong practicability. The target polymers can serve as new polymer biomaterial for use in the biotechnology area.
