MICELLIZATION BEHAVIOR COMPARISION OF POLYPEPTIDE GRAFT COPOLYMER AND BLOCK-GRAFT COPOLYMER IN ETHANOL

Poly(ethylene glycol)-block-poly(γ-benzyl L-glutamate)-graft-poly(ethylene glycol) (PEG-b-PBLG-g-PEG) copolymer and poly(γ-benzyl L-glutamate)-graft-poly(ethylene glycol) (PBLG-graft-PEG) copolymer were synthesized by the ester exchange reaction of PEG chain with PBLG-block-PEG cop...
