摘　　要：合成了聚羧酸系减水剂(TW-PS)。实验表明,TW-PS对水泥具有很好的分散性和分散保持性,其综合性能明显优于萘系和氨基磺酸系减水剂,与国外同类产品性能相当。Polycarboxylate acid type water--reducers named as TW--PS was synthesized. Experiment showed that the capability of TW-PS to disperse cement particles and maintain the flowability of concrete is supiror , the properties of TW--PS were obviously superior to those of the conventional naphthalene--based water--reducers and equal to those of the imported polycarboxylic acid type water--reducers.

关 键 词：聚羧酸系减水剂 共聚 混凝土
