A novel star-shaped integrated rubber of butadiene-isoprene-styrene tri-copolymer(SIBR) was prepared in the styrene(St)/isoprene(Ip)/butadiene(Bd) system with self-made N-multi-Li (simplified as Li) as initiator, cyclohexane as solvent and N-N-N′-N′-tetramethylethylenediamine(TMEDA) as polar modifier.
以自制氮官能化多锂(以下简称Li)为引发剂,N,N,N′,N′-四甲基乙二胺(TMEDA)为极性调节剂,环己烷为溶剂,对苯乙烯(St)、异戊二烯(Ip)、丁二烯(Bd)进行负离子聚合,合成了星形集成橡胶丁二烯-异戊二烯-苯乙烯三元共聚物(SIBR),研究了不同TMEDA/Li(摩尔比)下SIBR的聚合反应动力学。
