用Hofmann降解和Mannich反应对聚丙烯酰胺和聚(丙烯酰胺-丙烯酸共聚)S进行了连续反应，制得了低相对分子质量的聚(丙烯酸-乙烯基氨基甲基膦酸)S，并用1H-核磁共振、31P-核磁共振和显微分析进行了结构分析。对这些聚合物的阻垢性能进行了测试，发现其阻垢效果优于市售聚丙烯酸S，且随着氨基亚甲基膦酸基含量的增加，共聚物的阻垢性能增强。©2000 John Wiley&Sons，Inc.《应用理工学院学报》78：870-874,2000
Low molecular weight poly(acrylic acid-co-vinyl aminomethylene phosphonic acid)s were prepared by consecutively applying the Hofmann degradation and the Mannich reaction to polyacrylamide and poly(acrylamide-co-acrylic acid)s. 1H-NMR, 31P-NMR, and microanalysis were used for structural analyses. These polymers were tested as anti-scalent and they showed better anti-scalent effect than commercial poly(acrylic acid)s. The scale inhibition properties of copolymers increased with increasing amount of aminomethylene phosphonic acid groups. © 2000 John Wiley & Sons, Inc. J Appl Polym Sci 78: 870–874, 2000
