| Abstract: | Maleic anhydride(MA),allylic polyethylene glycol ether(XPEG),and methyl allylic sulfonic acid sodium(SMAS) as raw materials,a new polycarboxylic high-range water reducer with good workability and excellent performance was designed and synthesized by way of free radical water solution polymerization.The problem of poor workability,difficult pumping and casting work of ready-mixed concrete was solved.Infrared spectral analysis showed that molecular structure of synthetic product basically coincided with designed polycarboxylic high-range water reducer. |
