-benzyl ester) was synthesized by ring opening polymerization of
N
-carboxyl anhydride of
γ
-benzyl-
L
-glutamate (NCA) using the amino terminal macromolecule as an initiator. The y-benzyl ester groups in side chain were converted into hydrazide by hydrazine hydrate. Doxorubicin (DOX) was covalently loaded on the terpolymer
yielding nano micelles with DOX-loaded poly (
L
-glutamic hydrazide) as the core
and poly(
N
-isopropylacrylamide-
co
-poly ethylene glycol) as the hydrophilic shell. The micelles could be used as a drug carrier
showing temperature and pH dual responsive behaviors.
