Monodisperse polymers are polymers in which all polymer chains have the same degree of polymerization and molecular mass. Amphiphilic copolymers are copolymers in which the hydrophilic monomers and hydrophobic monomers copolymerize in a regular specific sequence. Unlike polydisperse amphiphilic block copolymers, monodisperse amphiphilic alternating copolymers can be precisely controlled in the self-assembly behavior and structure by changing the monomer sequence distribution and the balance of hydrophilic and hydrophobic chains. Herein, we report the synthesis of monodisperse amphiphilic copolymers composed of hydrophilic poly(ethylene glycol) and hydrophobic alkyl groups alternatively attached to poly(malic acid) using an iterative convergent method. We can compare the self-assembly behaviors of amphiphilic copolymers by GPC and DLS in water and organic solvents.
