Use of comb polymers for rheology control of inorganic binder compositions

摘要

The comb polymer is used to increase the flow rate and / or reduce the viscosity of the inorganic binder composition, wherein the comb polymer includes a backbone containing acidic groups and side chains associated with the backbone. And the number average molecular weight of all side chains is 120 to 1000 g / mol, and the molar ratio of acidic groups to side chains is in the range of 0.5 to 2.
