摘要：以丙烯酰胺（AM）和衣康酸（IA）为原料，采用自由基溶液聚合法合成了共聚物（IAPAM），用 FTIR、
1 HNMR、元素分析和 GPC 对其结构进行表征，并对其抗一价、二价阳离子降黏性能及抗氧化还原物质能力进

Abstract: Acrylamide (AM)/itaconic acid (IA) copolymer IAPAM was synthesized by free radical solution

polymerization method and characterized by FTIR, HNMR, elemental analysis and GPC. The ability to
resist reducing viscosity of monovalent and divalent cations and to resist redox substances were evaluated.

The results showed that the viscosity-average molecular mass of IAPAM was as high as 1.716×10 .
Compared with partially hydrolyzed polyacrylamide (HPAM), IAPAM had better viscosity reduction

2+
ability against monovalent and divalent cations. When the Na and Ca mass concentration was 30000 and
500 mg/L, the viscosity of IAPAM aqueous solution was 196.8 and 161.56 mPa·s, and the viscosity
reduction rate was 21.44% and 35.52%, respectively. The results of anti-oxidation and reduction substance

evaluation experiments indicated that IAPAM exhibited better resistance to degradation of Fe and S .

When the mass concentration of both Fe and S was 10 mg/L, the viscosity reduction rate was 23.67%
2+
and 0.56%. However, it took a certain time for IAPAM to stabilize the complexation of Fe , and the

oxidative degradation of Fe on the polymer could still be carried out when the complexation stability was
not reached.
