Upper critical solution temperature switchable micelles based on polystyrene‐<i>block</i>‐poly(methyl acrylate) block copolymers

Abstract The solubility behavior of well‐defined poly(methyl acrylate) homopolymers as well as polystyrene‐ block ‐poly (methyl acrylate) block copolymers is discussed in this contribution. A solubility screening in ethanol–water solvent mixtures was performed in a high‐throughput manner using parallel turbidimetry revealing upper critical solution temperature behavior for poly(methyl acrylate). Moreover, the self‐assembly behavior of the block copolymers into micellar structures was investigated by dynamic light scattering (DLS), transmission electron microscopy (TEM), and cryo ‐TEM revealing upper critical solution temperature switchability of the micelles, which was evaluated by DLS at different temperatures. © 2011 Wiley Periodicals, Inc.
