Amphiphilic double-brush copolymers (DBCs) with each graft site quantitatively carrying both a hydrophilic poly(ethylene oxide) (PEO) graft and a hydrophobic polystyrene (PSt) graft were synthesized by reversible addition-fragmentation chain transfer (RAFT) polymerization of styrene using a PEO-based norborene-functionalized RAFT agent, followed by ring-opening metathesis polymerization of the resulting diblock macromonomer. These DBCs were utilized as giant surfactants and polyfunctional RAFT agents in miniemulsion polymerization of St. Without using a cross-linker, well-defined polymeric nanolatexes with narrow size distributions were yielded; however, with the presence of divinylbenzene as the cross-linker, vesicular polymeric nanocapsules were obtained as the major product.
