| Abstract: | A series of diblock copolymers of styrene and 2 vinylpyridine have been synthesized successfully via sequential anionic polymerization.The results of GPC,FTIR,1H NMR and 13C NMR show that the products are diblock copolymers with high molecular weight 415×104 to 10 6×104 and narrow molecular weight distribution 1 19～1 66.The two phase structure of the copolymers is proved by the information obtained from DMA and DTA. |
