Owing to their inherent differences , consecutive “living” free radical polymerizations can yield graft and dendritic graft (dendrigraft) copolymers with multiple chain‐end functionalities such as that shown schematically on the right (PS = polystyrene), PBMA = poly( n ‐butyl methylmethacrylate). The first polymerization leads to the linear backbone, and subsequent polymerizations introduce grafted chains.
