Method for producing cement additive and hydrophilic graft polymer used therein |
| abstract |
PROBLEM TO BE SOLVED: To provide a novel cement additive having a high cement dispersibility with a small amount of addition and a method for producing a hydrophilic graft polymer used therefor. SOLUTION: The cement additive is a polyether containing an ethylenically unsaturated monomer containing an unsaturated carboxylic acid monomer having α, β-unsaturated dicarboxylic acid and / or an anhydride thereof as an essential component. It contains, as an essential component, a hydrophilic graft polymer having a weight average molecular weight of 6,000 or more obtained by graft polymerization of a compound. This hydrophilic graft polymer has α, It can be obtained by graft-polymerizing an ethylenically unsaturated monomer containing an unsaturated carboxylic acid monomer having β-unsaturated dicarboxylic acid and / or an anhydride as an essential component to a polyether compound. |
