| Abstract: | A series 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 DMA and the solid state NMR. Themorphology structure is closely related to the ratio between X.M.A and Xos. |
