摘要
全氟辛基乙基丙烯酸酯(PFMA)为疏水单体,与丙烯酰胺(AM)、丙烯酸(AA)通过自由基胶束共聚法制得氟碳型阻垢剂。研究了影响共聚反应的各种因素和变化规律,讨论了功能性单体的种类和含量对共聚物性能的影响,确定合理的聚合工艺条件。实验结果表明,在共聚反应温度为50℃、共聚反应时间为6 h、引发剂质量分数(占单体质量)为0.3%、AMPS质量分数为15%、含氟单体质量分数为0.5%及SMR值为7时,合成的三元共聚物具有优异的溶解性能。对共聚物的阻垢、缓蚀性能进行了测试。结果表明,该共聚物具有优良的阻垢缓释性能。
Fluorocarbon-modified polyacrylamide （FPAA） was prepared by free miceUar copolymerization of acrylamide （AM） , acrylic （AA） and Perfluorooctyl ethacrylate （PFMA）, initiated by redox initiation. The effect factors on the FPAA aqueous solution were discussed. The results show that there are strongly intermolecular hydrophobically associating interactions in the copolymer aqueous solution. When PFMA content, AA content, initiator content, reaction time, SMR, and FPAA molar fraction in aqueous solution are 0.5%, 15%, 0.3%, 4 h, 7, and 1 g/L, the synthesized copolymer has the outstanding dissolving performance. The results show that PFMA -AA-AM copolymer has good performances of scale inhibition and inhibition efficiency.
