摘要
应用１Ｈ－ＮＭＲ技术对系列丁腈橡胶（ＢＮＲ）标准物质的结构进行了表征。测定了丁腈橡胶标准物质中聚丁二烯链段中的顺式和反式结构含量、聚丁二烯链段中１，４加成聚合与１，２加成聚合的含量以及丁腈橡胶标准物质中结合丙烯腈的含量，测定的最大相对偏差为８．３％。
The structure of the certified reference material(CRM) of butadiene nitrile rubber (BNR) was characterized by 1H _ NMR. The relative amounts of cis _ and trans _ forms in the 1,4 _ polybutadiene segment, and also the relative amounts of 1,2 _ and 1,4 _ forms in the polybutadiene segment, as well as the amount of polymerized acrylonitrile were measured by NMR. The maximum relative deviation of the measurements is 8.3%.
