| 摘 要： | 在连续聚合工艺条件下,采用调节剂四氢呋喃(THF)和复合调节剂对溶聚丁苯橡胶(SSBR)的乙烯基含量进行调节.结果表明,SSBR的乙烯基含量与THF/n-BuLi的相关性不强,而与THF的用量呈现较好的线性相关;与THF调节体系相比,复合调节体系对乙烯基结构的调节能力更强;连续聚合的SSBR相对分子质量分布宽,综合性能优于间歇聚合产品,其中高苯乙烯基和高乙烯基SSBR具有较高的抗湿滑性能.

| Abstract: | Under the condition of continuous solution polymerization,tetrahydrofuran(THF) and complex modifier were used to adjust vinyl content in solution-polymerized styrene-butadiene rubber(SSBR).The results showed that the content of vinyl of SSBR was more linearly correlated with amount of THF than THF/n-BuLi(mole ratio),and the control capability of complex modifier for vinyl content was more effective than that of THF.The relative molecular mass distribution of continuously polymerized SSBR was wider,general p... |
