Abstract:
With a high-resolution 1H-NMR the features of solution-SBRs chain structures have been analyzed and made quantitative calculations of the chemical composites, inparticular, the contents of butadiene isomers have been made. It is reveal that the Bayer solution-SBR, whose performance is highly recognized inthe tire industry, has a high content of cis-1,4 butadiene isomers, allow content of trans-1,4 butadiene isomers, and a medium contents of 1,2add butadiene isomers and styrene units, as well as that the butadiene isomers display orderly characteristics in the sequence. The above structural features determine that Bayer solution-SBR can play good role in the balance of the low heat building up, antiwetskip and antiwear properties of green tire.

摘要:
用高分辨 1H-NMR研究了不同溶聚丁苯橡胶链化学结构的特征,并对其中的化学组成特别是丁二烯异构体含量进行了定量计算.揭示了轮胎工业中公认性能优良的拜尔溶聚丁苯橡胶具有较高的cis-1,4丁二烯异构体含量,而trans-1,4丁二烯异构体含量较低, 1,2add丁二烯异构体含量和苯乙烯含量比较适中,而且丁二烯异构体具有一定的序列有序性.正是这些结构因素,决定了拜尔溶聚丁苯橡胶能够对绿色轮胎低生热、抗湿滑和耐磨性能起到了最佳平衡作用.
