Polymeric micelles were prepared by dropping ethanol into solutions containing poly(γ—benzyl L—glutamate)-poly(ethylene oxide)block copolymer(PBLG-b—PEO)
nuclear magnetic resonance(1H-NMR)spectroscopy and infra-red difference spectroscopy(IR)were used to investigate the influence of PBLG chain conformation on the self-assembly behavior of PBLG-b-PEO.The experimental resuhs revealed that PBLG—b—PEO could associate into polymeric micelles in ethanol solutions.The introduction of TFA not only changes the conformation of PBLG segments
but also increases the critical micelle concentration
and further affects the morphologies of the formed micelles.
