Powdery cement dispersant |
| abstract |
The present invention provides a polycarboxylic acid type powdery cement dispersant having superior dispersing performance. The present invention provides a powdery cement dispersant which contains a polycarboxylic acid type copolymer having a repeating unit (I) derived from an unsaturated polyalkyleneglycol ether type monomer (a) and a repeating unit (II) derived from an unsaturated carboxylic acid type monomer (b) and having neutralization degree of carboxyl groups contained in the polycarboxylic acid type copolymer is not higher than 50%. The present invention also provides a powdery cement dispersant which comprises a polycarboxylic acid type copolymer comprising a repeating unit (I) derived from an unsaturated polyalkyleneglycol ether type monomer (a) and a repeating unit (II) derived from an unsaturated carboxylic acid type monomer (b), and the unsaturated polyalkyleneglycol ether type monomer (a) comprising an alkenyl group having 4 to 8 carbon atoms. |
