| 摘 要： | 采用水溶液自由基聚合法，以衣康酸（IA）为单体，在不同反应温度下经引发剂引发，聚合得到了一系列衣康酸均聚物（PIA）。采用红外光谱、凝胶渗透色谱、碘量法等对PIA进行表征，并评价其阻垢和缓蚀性能。结果表明，重均相对分子质量为1800~2700的PIA性能良好，当其添加量（ρ）为8 mg/L时，对CaCO3的阻垢率超过65%，与4 mg/L Zn2+复配后，其对碳钢的缓蚀率超过90%。

PREPARATION OF ITACONIC ACID HOMOPOLYMER AND ITS ANTI-SCALE AND CORROSION-INHIBITION PERFORMANCE |
| |
| Abstract: | A series of itaconic acid homopolymers (PIA) were synthesized by free radical polymerization in aqueous solution, using itaconic acid as monomer and initiator at different reaction temperature. The prepared PIAs were characterized by IR, gel permeation chromatography (GPC) and iodometry, and their anti-scale and corrosion-inhibition performance were evaluated. The results showed that the PIA with average molecular weight of 1 800-2 700 had excellent performance ,the anti-scale rate for CaCO3 was more than 65%, and the corrosion-inhibition rate for carbon steel was more than 90% . |
