| titleOfInvention |
Macromolecular, amphiphilic compounds as water retention agents for construction chemistry systems, in particular for well cementing |
| abstract |
The water retention agents according to the invention are outstandingly suitable as additives in construction chemistry systems and in the development, exploitation and completion of underground mineral oil and natural gas deposits and in deep wells, their effect being particularly advantageous at increased temperatures and because of their lack of influence on the rheological properties of the well slurries. |
