Abstract

Abstract: Polyacrylamide/poly(γ-benzyl-L-glutamate)(PAM-g-BLG) amphiphilic graft copolymers were synthesized by ring-opening polymerization of N-carboxy-γ-benzyl-L-glutamate anhydride(BLG-NCA) in N,N-dimethylformamide(DMF) initiated by polyacrylamide. The structure of the copolymers was determined via IR, ¹H NMR and GPC. The fluorescence technique was used to determine micellization and the critical micelle concentrations(CMC) of copolymer in water. The diameter and distribution of micelles were characte-rized by DLS and its shape was observed by TEM. The results show that BLG-NCA could be initiated by polyacrylamide to produce graft copolymer. The round nano-micells were formed by these copolymers in water. The CMC of copolymer solution and the size of micell were reduced with the increase of the proportion of hydrophobic parts.

Key words: Poly(γ-benzyl-L-glutamate), Amphiphilic graft copolymer, Ring-opening polymerization, Critical micelle concentration
