We describe the synthesis and characterization of three-arm star block copolymers based on polystyrene, poly(ethylene oxide), poly(ϵ-caprolactone), poly(methyl methacrylate), poly(tert-butyl methacrylate) and poly(L-lactide) blocks. The copolymers were obtained by a route consisting of two successive initiation steps on functional macroinitiator. Some results on micellization and crystallization are given. They indicate an increase in the miscibility of different incompatible blocks.
