摘　　要：随着聚羧酸盐减水剂的不断发展,马来酸酐在其合成中的应用也越来越多。根据马来酸酐与丙烯酸(以及甲基丙烯酸)各自的特性和聚羧酸盐减水剂合成的技术要求,分析了它们在合成过程中的作用和主要差别,并概述了马来酸酐在合成中的应用情况,最后提出了马来酸酐在合成中应用的几点建议。马来酸酐及其酯的分子结构和化学活性独特,应用于聚羧酸盐减水剂的合成必将有广阔的前景。With the unceasing development of polycarboxylate superplasticizers, maleic anhydride is used more and more in its synthesis. In the paper the effects and main differences of maleic anhydride and acrylic acid （and methacrylic acid） in the synthesis of polycarboxylate superplasticizers are analyzed according to their respective characteristics and technical requirements for synthesis. The application status of maleic anhydride in the synthesis of polycarboxylate superplasticizers is summarized, and some suggestions on the research about its application are put forward at last. Thanks to the particular molecule structure and chemical activity of maleic anhydride and its ester, the applica- tion in synthesizing polycarboxylate suoerolasticizers will certainly have broad prospects.
