On the basis of patent of multilithium initiator , star-high vinyl polybutadiene (S-HVBR) was synthesized by one-step addition process , with cyclohexane as solvent and tet rahydrofuran , diethylene glycol dimethyl ether and ethylene glycol dimethyl ether as additives. The results showed that when S-HVBR was synthesized with multilithium initiator , the content of 1 ,2-structure could be cont rolled between 70 %~80 % , the molecular weight distribution was more wide and the species and the content of microst ructure modifying additives as well as the temperature all had a great influence on the microst ructure of S-HVBR.
