Abstract:
The present invention provides a method for preparing a polymer and a use of the polymer. The resulting polymer is used as a dispersant for an aqueous dispersion of a hydraulic binder and/or a latent hydraulic binder, such that water-reducing rate is improved, and suitable control of air content can be achieved, thereby improving the strength of concrete. The method for preparing a polymer includes polycondensation of a polyether macromonomer A of a specific structure, a monomer B and an aldehyde C to obtain the polymer. The monomer B is phenylsulfonic acid, p-/o-aminophenylsulfonic acid, p-/o-hydroxylbenzoic acid, p-/o-aminobenzoic acid, p-/o-hydroxylphenylsulfonic acid, or a phosphoric acid group or phosphorous acid group-containing monomer of a specific structure. A molar ratio of the polyether macromonomer A and the monomer B is 1:(0.5 to 12).
