摘要:
采用核磁共振氢谱测定了苯乙烯-共轭二烯烃嵌段共聚物及其加氢反应产物氢化苯乙烯-共轭二烯烃嵌段共聚物(HSBC)的微观结构和组成,计算了HSBC的苯环加氢度,并与紫外光谱法的计算结果进行对比分析。结果表明,与紫外光谱法相比,核磁共振氢谱法具有步骤简单、快捷高效等优势,由其计算所得HSBC的苯环加氢度与紫外光谱法计算结果具有较好的一致性。
Abstract:
The microstructure and composition of styrene-conjugated diene block copolymer and its hydrogenation product hydrogenated styrene-conjugated diene block copolymer (HSBC) were determined by nuclear magnetic resonance spectroscopy, degree of benzene ring hydrogenation of HSBC was calculated and compared with the calculation result of ultraviolet spectrum. The results showed that compared with the ultraviolet spectrum, the nuclear magnetic resonance spectroscopy had the advantages of simple steps, fast and efficient, and calculated degree of benzene ring hydrogenation of HSBC was in good agreement with the calculation results of UV method.
