摘要：

Using methoxy polyethylene glycol methacrylate (MPEGMA), butyl acrylate (BA), Methyl allyl sulfonate (SMAS) as the raw materials, we can compose them to multipolymer in redox system. Through analyzing the factors and adjustment of orthogonal experimental results, the optimum technology of synthesis are shown as follows: n(MPEGMA):n(BA):n(SMAS)=5:12:2, n(H2O2)/n(Vc)=6, and the reaction temperature is 30 degrees C. When the volume of superplasticizer is 0.42%, water cement ratio is 0.3; the initial fluidity of cement paste can get to 238mm, and within 1 hour without any loss.
