Abstract: Aseries of diblock copolymers of styrene and methyl methacrylate weresynthesized via sequential anionic polymerization.The products are diblock copolymers with highmolecular weight and narrow molecular weight distribution.The microphase-separatingstructure is proved by the information obtained from DMAand the solid state NMR.Themorphology structure is closely related to the ratio between XPMMAand XPS.

Key words: Block copolymer, Polystyrene, poly (methyl methacrylate), Anionic Polymerization morphology
