摘要
采用Ｃ１３ＮＭＲ光谱研究了丙烯酰胺丙烯酸钠乳液聚合过程中共聚物的组成、序列分布，并与Ｂｅｒｎｏｕｌｉａｎ统计模型进行了比较。结果表明，此种共聚物呈三元序列分布。在任意转化率下，共聚物的组成均不发生漂移，而且在低转化率下，与Ｂｅｒｎｏｕｌｉａｎ统计模型吻合得很好。
The composition and sequence distribution of acrylamidesodium acrylate copolymer were determinded by C_13 NMR spectra. Results showed that the copolymer is in triad sequence distribution and at low conversion of polymerization ,it is in good agreement with that calculated from Bernoulian statistics, the composition of the copolymer is constant at any conversions.
