Block copolymers of polymethylphenylsilane (PMPS) and polystyrene (PS) have been successfully prepared by the condensation of α,ω‐dichloro‐polymethylphenylsilane with polystyryl‐lithium. These new materials have been characterized by UV spectroscopy, 29Si‐NMR, and size exclusion chromatography. These block copolymers show a good emulsifying activity to compatibilize blends of the two homopolymers (PMPS and PS).
