Highly symmetric poly(styrene)-block-poly(butadiene-stat-styrene)-block-poly(styrene) copolymer prepared in a non-stop one-pot RAFT polymerization in miniemulsion

Symmetric SBS latexes are prepared for the first time following a non‐stop one‐pot reversible addition fragmentation chain transfer (RAFT) polymerization in miniemulsion. The symmetry of the SBS is studied spectroscopically and chemically, which opens possibilities for further functionalizations. The morphology of the resulting nanoparticles is presented. The process can be realized at the pilot plant scale and is expected to be extrapolable to other monomers and to different polymerization methods.
