采用磺甲基化反应对聚丙烯酰胺进行了改性。探讨了反应条件对产物性能的影响。
The polyacrylamide was modified by sulfomethylation and the effects of reaction conditions on properties of modified product were investigated.
实验证明：磺甲基化聚丙烯酰胺的抗盐性和水溶性均得到改善，可用作油井水泥降失水剂。
The experimental results were indicated that salt-tolerance and thermal stability were improved, therefore, it can be used as a water loss control additive in oilwell cement.
