Abstract
Well‐defined diblock copolymers have been prepared in which three different ferrocene‐based monomers are combined with 1,1‐dimethylsilacyclobutane (DMSB) and 1‐methylsilacyclobutane, respectively, as their carbosilane counterparts. Optimized procedures are reported for the living anionic chain growth following sequential monomer addition protocols, ensuring narrow polydispersities and high blocking efficiencies. The DMSB‐containing copolymers show phase segregation in the bulk state, leading to micromorphologies composed of crystalline DMSB phases and amorphous polymetallocene phases.Keywords
