SYNTHESIS AND CHARACTERIZATION OF POLY(L-GLUTAMIC ACID-co-L-ASPARTIC ACID)

摘要

Poly(amino acid)has been widely utilized in drug delivery,tissue engineering and biomedical materials.The biomaterials based on poly(glutamic acid)are usually modified via copolymerization with other monomers such as L-aspartic acid to improve the uncontrolled degradation rate.The ring-opening homo- and co-polymerization ofγ-benzyl-L-glutamate N-carboxyanhydride(BLG-NCA)andβ-benzyl-L-aspartate N-carboxyanhydride(BLA-NCA)were carried out in solution by using triethylamine(TEA)as initiator.The BLG-NCA homo...
