The straightforward synthesis of a polystyrene‐ arm ‐polybutadiene‐ arm ‐poly(methyl methacrylate) triarm star copolymer has been successfully realized by a sequence of reactions which involves the sequential addition of a living polybutadienyllithium to a polystyrene macromonomer with a terminal 1,1‐diphenylethylene unit and subsequent polymerization of methyl methacrylate. The high‐molecular‐weight polystyrene‐ arm ‐polybutadiene‐ arm ‐poly(methyl methacrylate) star copolymer shows microphase separation into three phases.
