Abstract (en)
[origin: WO2021105187A1] The invention relates to the use of branched copolymers of general structure (I) as additives for increasing the flow speed and reducing the viscosity of mineral binder compositions. A further aspect of the invention relates to mineral binder compositions containing at least one branched copolymer of general structure (I).
