摘要
低分子量聚丙烯酸(PAA)具有良好的阻垢性能,本文以Na2S2O8-Na HSO3氧化还原体系为引发剂,CTA为链转移剂,LA为分子量调节剂,研究了聚合反应条件对产物粘均分子量的影响。通过控制引发剂的量、还原剂的量、聚合反应温度、单体浓度、链转移剂及分子量调节剂的量,从而获得低分子量聚丙烯酸的较佳合成条件,同时对其进行了阻垢性能测试。实验结果表明:合成出的聚丙烯酸分子量在2000左右,且具有较高的阻垢分散性能。
Low molecular weight polyacrylic acid(PAA) has good scale inhibition performance. In this article, we prepared the target product with Na2S2O8-Na HSO3 redox system as initiator, CTA as chain transfer agent and LA as molecular weight regulator. The polymerization reaction conditions on the viscosity average molecular weight were studied. A better synthesis condition of low molecular weight poly(acrylic acid) was obtained by controlling the amount of initiator, the polymerization temperature, the monomer concentration, the amount of the chain transfer agent and additive agent, and its scale inhibition performance was also tested. The experimental results showed that the synthesis of poly(acrylic acid) molecular weight was about 2000, and it had high scale inhibition and dispersion properties.
