Abstract

Amphiphilic copolymers based on polystyrene (PS) and poly(ethylene oxide) (PEO) were assembled in branched architectures with a view of obtaining samples exhibiting little fluctuation in size and composition. "Living"/controlled polymerizations - anionic for ethylene oxide and atom transfer radical one for styrene - were associated with highly selective branching reactions towards this end. Another means to generate original branched amphiphilic copolymers was to resort to the ring-opening metathesis (co)polymerization of macromonomers. No less than twelve novel architectures based on PEO and PS - regular stars, stars, dendrimer-like stars, H-type copolymers, miktoarm stars, janus-type spheres, etc. - were engineered through these techniques.
