Powder dispersant for hydraulic compositions |
| abstract |
The present invention provides a powdery dispersant for hydraulic compositions, which is excellent in pumping before drying and in pressure resistance and humidity resistance, which comprises one or more copolymers obtainable by polymerizing a specific vinyl monomer (a) such as an ethylenically unsaturated carboxylic acid derivative having a polyoxyalkylene group with a specific vinyl monomer (b) such as (meth) acrylic acid etc., wherein the average number of C 2-4 oxyalkylene groups or oxystyrene groups added is 2 to 300, (a) / [(a) + (b)] × 100 ranges from 15 to 45 (mole-%), and at least a part of the copolymers are monovalent metal salts. |
