工业循环水阻垢剂的核磁共振 分析Ⅰ.聚合物类阻垢剂的分析

NMR Analysis of Scale Inhibitors for Industrial Circulating Water by NMR Ⅰ. Analysis of Polymeric Scale Inhibitors

采用１３Ｃ、３１Ｐ核磁共振谱分析了４种聚丙烯酸型循环水阻垢剂。研究了它们的端基结构、ｐＨ值对谱峰的影响。

C and 31P NMR spectra were employed to study the structure of four scale inhibitors of polyacrylate type. Their end group structure,the effect of pH on their NMR peaks,the structure of hydrolysates and the various types of phosphonic groups in the copolymer chains were investigated.
