[en] The synthesis of a new pH-sensitive amphiphilic A2B mikto-arm star-shaped aliphatic copolyester (with A = PCL and B = tertiary amine-bearing PCL) with two hydrophobic arms and one hydrophilic arm when protonated at pH = 5.5. The copper mediated azide-alkyne cycloaddition was used for the synthesis of the star copolyester and to impart the pH sensitivity to the hydrophilic arm by grafting of tertiary amine groups onto azide bearing PCL chain. The formation of polymersomes in water at pH 5 was assessed by DLS and TEM analyses.
