A micellization study of medium chain length poly(3-hydroxyalkanoate)-based amphiphilic diblock copolymers

► Biocompatible bacterial polyester-based amphiphilic copolymers are synthesized. ► Well-defined micelles ranging from 44 to 90 nm with low polydispersity are obtained. ► The amorphous and hydrophobic nature of the polyester provides very stable micelles. ► The micelles exhibit good stability at physiological ionic strength.
