摘要
阐述了聚氧乙烯（或丙烯）类减水剂的合成方法及其性能。该减水剂以四氢呋喃为溶剂，在苯乙烯马来酸酐共聚体上引入聚氧乙烯（或聚氧丙烯）基，从而增大其表面活性，增强其对水泥的分散能力，可有效地控制混凝土的坍落度损失，提高混凝土的早期强度。
Synthesis of polyoxyethylene or polyoxypropylene series water reducers and thier properties are described.This new water reducer is copolymerized on the basis of styrenemaleic anhydride with polyoxyethylene or polyoxyacrylic derivatives introduced and with THF used as solution, thus enhancing its surface activity, improving its dispersing capacity on cement, effectively controlling concrete slump loss and increasing concrete early strength.
