Method for producing polymer |
| abstract |
Dispersant, cement admixture, and method for producing polymer with controlled molecular weight distribution that can be suitably used for cement composition, and dispersant and cement using polymer obtained by the production method It is an object to provide an admixture and a cement composition. In the presence of a polymerization initiator system comprising a metal complex (A) having ruthenium as a central metal and an α-halogenocarbonyl compound and / or an α-halogenocarboxylic acid ester (B). An unsaturated monomer (M) including an unsaturated monomer (IM) having a polyoxyalkylene chain is polymerized. The resulting polymer has a narrow molecular weight distribution, a high molecular weight part that aggregates cement and a low molecular weight part that does not contribute to cement dispersion performance, and a large amount of molecular weight part that contributes to cement dispersion performance. Dispersion performance is improved. [Selection figure] None |
