摘　　要：聚丙烯酸的用途与其分子量的大小有着密切的关系,而低分子量的聚丙烯酸具有良好的水溶性和较大的极性,能够结合水中的钙、镁等多价离子形成可溶的链状阴离子,因此,用其作水质稳定剂具有显著的防垢效果。本文综述了低分子量聚丙烯酸钠的聚合原理、合成方法及其研究现状,并对其在各领域应用前景作了简要介绍。The application of polyacrylic acid depended on the size of the molecular weight.The polyacrylic acid with low molecular weight,good water soluble and larger polarity,can combine to the polyvalent metal ion such as calcium and magnesium ions,and formation soluble anionic.Therefore,using polyacrylic acid with low molecular weight as water stabilizer had significant inhibition effect.The polymerization mechanism,synthesis methods and research status of the polyacrylic acid with low molecular weight were reviewed.In addition,the application prospect of polyacrylic acid was briefly introduced.
