Method for producing cement dispersant |
| abstract |
(57) [Summary] Polyalkylene glycol mono (meth) A reaction mixture including a monomer mixture containing an acrylate monomer and (meth) acrylic acid, a polymerization initiator and water is charged into a reaction vessel so as to have a solid content concentration of 50 to 90% by weight. Characterized in that the polymerization is carried out at a polymerization temperature of 42 to 70 ° C., preferably by gradually increasing the temperature (meta). A method for producing an acrylic acid-based cement dispersant. [Effect] A high-performance cement dispersant having a narrow molecular weight distribution can be produced in a short time by a simple operation without requiring a special device. |
