【Abstract】 In this paper,DVB was first polymerized with butadiene using butyllithium in cyclohexane to form soluble multi melic initiator.After the completion of copolymerization of butadiene and styrene with this kind of initiator,a kind of branching structure SSBR was obtained.Mixing the polymer solution with aromatic oil or naphthenic oil,the oil extended SSBR could be prepared.It was shown that values of MWD were increased with the increase of mole ratio of ,and prepared oil extended SSBR had excellent mechanical properties.更多还原
