| 摘 要： | 以正丁基锂（ｎ－ＢｕＬｉ）为引发剂，环己烷为溶剂，ＴＨＦ、２Ｇ、ＴＭＥＤＡ为结构调节剂，合成了溶液聚合二元丁二烯、苯乙烯共聚物。研究结果表明：合成的共聚物不同嵌段微观结构不同，和普通溶聚丁苯橡胶相比，该共聚物不仅具有良好的物理机械力学性能同时具有低滚动阻力和抗湿滑性能。

| Abstract: | New types of solution polymerized rubber with two styrenebutadiene copolymer blocks were synthesized in this paper.An organolithium compound can be used as polymerization initiator,various types ethers and amines may be used as controlling agent for vinyl content in the butadiene portion,such as THF,2G and TMEDA.Synthesized twoblock copolymers have excellent rolling resistance and wet skid resistance as well as good mechanical properties by comparision with the ordinary SSBR. |
