It is successfully realized that block copolymers are synthesized via metathesis polymerization followed by free radical polymerization. This method is performed using styrene and norbornene, one block is synthesized using the Grubbs second catalyst in the presence of chain transfer agents, and the subsequent polymerization of styrene is initiated by azo compounds to complete the additional blocks in the copolymers. The use of free radical polymerization instead of controlled radical polymerization or ionic polymerization can be potentially superior for industrialization. As a result, the molecular weights of the block copolymers ranging from 10.4 to 54.3 KD and polydispersity indices ranging from 1.30 to 1.91 are obtained. In principl
