苯乙烯无规均匀分布的中乙烯基溶聚丁苯橡胶的合成及性能
采用负离子活性聚合法,用四氢呋喃-叔丁基氧钾二元调节体系合成了苯乙烯无规均匀分布的中乙烯基溶聚丁苯橡胶（SSBR）,考察了调节体系对苯乙烯无规分布的均匀性、1,2-结构含量、聚合速率以及产物物理机械性能和动态力学性能的影响。结果表明,叔丁基氧钾对苯乙烯无规分布的均匀性起主要调节作用,四氢呋喃对1,2-结构含量起主要调节作用;增加四氢呋喃和叔丁基氧钾的用量则聚合速率加快;与常规SSBR相比,所合成苯乙烯无规均匀分布的中乙烯基SSBR的综合性能更好。...

| Notes | Medium vinyl solution polymerized bu- tadiene-styrene rubber （SSBR） with uniform and random distribution of styrene unit was synthesized with tetrahydrofuran （ THF）-potassium tert-butoxide （t-BuOK） as dual regulator system by anionic living polymerization. The influences of THF-t-BuOK on the uniformity of random distribution of styrene, vinyl content, polymerization rate, the mechanical and dynamic mechanical properties of obtained product were investigated, The results showed that t-BuOK had main effect tion uniformity on the regulation of styrene unit, of random distribuand THF on themodulation of vinyl content. With increasing the amount of THF and t-BuOK, the reaction rate was accelerated. Compared with the conventional SSBR, the medium vinyl SSBR with uniform and random distribution of styrene unit had better comprehensive properties. 62-1036/TQ ZHANG Ying , WANG Hao, ZHENG Rui, WANG Meng, LIU Hua-hua,ZHAO Su-he, ZHANG Xing-ying（1. a.
