Synthesis of amphiphilic polyethylene-b-poly(l-glutamate) block copolymers with vastly different solubilities and their stimuli-responsive polymeric micelles in aqueous solution

Amphiphilic polyethylene-block-poly(l-glutamate) (PE-b-PGA) diblock copolymers were synthesized. The spherical polymeric micelles self-assembled in aqueous solution exhibited pH- and ionic strength responsibility.
