Chun-qing,MU Rui-feng ABSTRACT In this paper,DVB was
first polymerized with butadiene using butyllithium in cyc lohexane to form soluble multi
melic initiator.After the completion of copolymer ization of butadiene and styrene with
this kind of initiator,a kind of branchin g structure SSBR was obtained.Mixing the polymer
solution with aromatic oil or na phthenic oil,the oil-extended SSBR could be prepared.It
was shown that values o f MWD were increased with the increase of mole ratio of [DVB]/[n-BuLi],an
d prepared oil-extended SSBR had excellent mechanical properties. 作者简介:薛宏(1969-),男,吉林省长春市人,讲师,博士,主要从事新型弹性体及活性
