Title:
PREPARATION METHOD FOR POLYMER AND APPLICATIONS THEREOF
Document Type and Number:
WIPO Patent Application WO/2017/113991
Kind Code:
A1
Abstract:
Provided in the present invention are a preparation method for a polymer and applications thereof. The polymer prepared is used as a dispersant for the aqueous dispersion of a hydraulic binding agent and/or a latent hydraulic binding agent, increases bleeding rate, and implements appropriate control of gas content, thus enhancing the strength of concrete. The preparation method for the polymer is such that specifically-structured polyether macromonomer A, monomer B, and aldehyde C undergo a condensation reaction to produce the polymer, where monomer B is benzenesulfonic acid, P/O-aminobenzenesulfonic acid, P/O-hydrobenzoic acid, P/O-aminobenzoic acid, P/O-hydroxybenzenesulfonic acid, or a specifically structured monomer containing a phosphoric acid or phosphorous acid group, and the molar ratio of polyether macromonomer A to monomer B is 1:0.5-12.
