| titleOfInvention | Cement Admixtures and Manufacturing Method Thereof |
| abstract | Provided is a method for producing a copolymer for cement admixtures which can easily produce a plurality of copolymer blends having different monomer compositions in one polymerization operation and which has excellent sensitivity and / or retention. A method for producing a copolymer for cement admixtures having a step of polymerizing a monomer component comprising an unsaturated polyalkylene glycol ether monomer (A) and an unsaturated organic acid monomer (B), wherein the unsaturated polyalkylene is previously added to the reaction vessel. The unsaturated organic acid monomer (B) is added to the glycol ether monomer (A) by changing the addition rate at least once to polymerize the unsaturated polyalkylene glycol ether monomer (A) and the unsaturated organic acid monomer (B). Disclosed is a method for preparing a copolymer for cement admixtures having a step. |
