We report synthesis of branched multiblock macromonomers (BMMMs) via single monomer unit insertion (SUMI) in the reversible addition-fragmentation chain transfer (RAFT) process. By inserting a norbornene functionality in the middle of a polymer chain, BMMMs composed of A-b-B/B’-C architecture can be successfully synthesized. Ring-opening metathesis polymerization (ROMP) of BMMMs produces Janus core-shell bottlebrush polymer possessing a segregated core with two different corona chains. Self-assembly of Janus core-shell bottlebrush polymers characterized by small-angle X-ray scattering and transmission electron microscopy will be discussed in detail.
