Effect of Hydrophilic Monomer Distribution on Self‐Assembly of a pH‐Responsive Copolymer: Spheres, Worms and Vesicles from a Single Copolymer Composition
Résumé
Copolymers of acrylic acid (AA) and butyl acrylate (BA) with constant overall composition (1:1 AA:BA) and controlled composition profiles (gradient, asymmetric diblock and asymmetric triblock) show dynamic pH-responsive self-assembly behavior, with reversible changes in size and formation of sphere, worm and vesicle morphologies, in contrast to the frozen micelles formed by poly(AA-block-BA) block copolymers.
