Application

Polystyrene-block-polyacrylic acid is a diblock copolymer commonly used for making polymeric vesicles (polymersomes) and other encapsulation applications.; This was generated through RAFT polymerization;and contains end-group functionalization that can be used to generate a triblock copolymer or modified for ligation. The 2-(Dodecylthiocarbonothioylthio)-2-methylpropionic acid RAFT agent CTA is especially suited for the polymerization of styrene;acrylate and acrylamide monomers.

Vesicles are microscopic sacs that enclose a volume with a molecularly thin membrane. The membranes are generally self-directed assemblies of amphiphilic molecules with a dual hydrophilic-hydrophobic character. Biological amphiphiles form vesicles central to cell function and are principally lipids of
