Abstract: The poly(butadiene-b-methyl methacrylate)copolymer(PBD-b-PMMA)were synthesized by anionic polyfmerization method.The results of 1HNMRand FTIRshow that the products are block copolymers.The studies on copolymer by DMAand TEMdemonstrate that the block copolymers are microphase separation, that is, the polybutadiene phase and polymethyl methacrylate phase were formed.The molecular weight of copolymer and solvent do not have significant effects on the morphologies of copolymer, The morphologies of copolymer are dependent on structures of copolymers.
