摘要
研究固体核磁共振法测定硫化胶中的丁苯橡胶(SBR)微观结构。通过固体核磁碳谱解析,对丁苯胶中苯乙烯、1,2-乙烯基、1,4-丁二烯的特征峰进行归属并建立了计算3种结构的定量方法,该方法适用于单一丁苯胶也适用于异戊胶/丁苯胶等并用胶,分析结果准确,操作简便。
In this study,the microstructure of styrene-butadiene rubber(SBR)in the cured rubber was investigated by solid-state NMR method.The characteristics of styrene,1,2-vinyl and 1,4-butadiene in styrene-butadiene rubber(SBR)were analyzed to establish a quantitative method for calculating the three structures.The method can be used in cured SBR and SBR/NR blends,The results show that it is characterized by good accuracy and simple operation.
