USE OF COMB POLYMERS FOR CONTROLLING THE RHEOLOGY OF MINERAL BINDER COMPOSITIONS |
| 摘要 |
A comb polymer is used for increasing the flow rate and/or reducing the viscosity of a mineral binder composition, where the comb polymer has a main chain including acid groups and there are pendent chains linked to the main chain, and where the average number-average molar mass of all of the pendent chains is from 120 to 1000 g/mol and the molar ratio of the acid groups to the side chains is in the range from 0.5 to 2. |

1. A comb polymer used for increasing the flow rate and/or for reducing the viscosity of a mineral binder composition, the comb polymer having a main chain comprising acid groups, and side chains being attached on the main chain, with the number-average molecular weight (Mn) of all side chains being 12 0-1000 g/mol, and with the molar ratio of the acid groups to the side chains being in the range of 0.5-2. |
