Article Preview

Using esterification-polymerization two-steps synthesis method, two kinds of comb-like polycarboxylate agents of BT and JS were synthesized by controlling acid-ester ratio. The adsorption characteristics of Ca2+ ions on comb-like polycarboxylate polymers in the CaCl2 solution were studied. The results indicated that the adsorption behavior was closely related to the structure of polymers, the adsorption power of JS with water-reducing structure was strong, while weak with slump loss resisting polymers BT. The adsorption behavior was also in connection with the acid-ester ratio of polymer structure, the higher the acid-ester ratio is, the greater the absorption power; On the contrary, it will be smaller.
