摘要
利用 1HNMR、13CNMR及DEPT(无畸变极化转移增强 )核磁共振技术研究了苯乙烯 -马来酸酐共聚物(SMA)的序列结构和组成 ,并比较了几种核磁共振实验技术对分析SMA结果的准确性 ;实验表明1HNMR是分析组成的简单、快速而有效的方法 。
The monomer sequence distribution and the compositions of styrene-maleic anhydride copolymer has been investigated by 1 H NMR, 13 C NMR and DEPTtechnique.The experimental results showed that 1 H NMR was a simple,fast and useful technique for analyzing composition,and DEPT was more accurate than 13 C NMR for studying the monomer sequence distributions.
