利用水泥粉磨过程中的机械力促使水解聚马来酸酐（H PM A ）与聚乙二醇单甲醚（M PEG ）进行酯化反应形成聚羧酸助磨剂。试验研究了 H PM A、M PEG、H PM A 与 M PEG 的混合物、H PM A与M PEG 的反应合成物对水泥助磨效果以及对砂浆性能的影响。结果表明，H PM A 与M PEG都有一定的助磨性，H PM A与M PEG的混合物和反应合成物具有更佳的助磨性能，且可以改善水泥砂浆的流动性能和显著提高水泥砂浆的早期强度。激光拉曼光谱测试表明 H PM A 与M PEG的混合物和反应合成物与水泥共同粉磨后吸附在水泥颗粒表面，具有相似的拉曼位移图谱。

Hydrolyzed polymaleic anhydride (HPMA) and polyethylene glycol monomethyl ether (MPEG) synthesized a kind of polycarboxylic grinding aid ,the esterification was prompted by the mechanical force during the process of cement grinding .The effects on cement grinding and mortar property were tested from HPMA ,MPEG ,the mixture of HPMA and MPEG ,and the resultant of HPMA and MPEG .The results showed that the mixture of HPMA and MPEG and the resultant of HPMA and MPEG had better grinding performance than HPMA and MPEG ,and which can improve the fluidity and early strength of cement mortar .Laser Raman spectrum tests showed that the resultant of HPMA and MPEG had a similar Raman shift spectrum with the mixture of HPMA and MPEG ,when they were adsorbed on the cement particle surface after co‐grinding .
