Abstract: The present invention pertains to the use, in the manufacture of an aqueous formulation with a hydraulic binder base, of a combination of at least one comb-branched copolymer having a (meth)acrylic skeleton, onto which are grafted side-chains terminated by a hydrophilic group, and at least one ASE acrylic polymer. This results in improving the workability of said formulation, without causing a segregation phenomenon.

Abstract: The present invention relates to a continuous process for preparing a comb polymer, without organic solvent, by esterification and/or amidification of an acidic homopolymer or copolymer, which consists in performing the esterification and/or amidification of said homopolymer/copolymer by reaction at elevated temperature in the mixing and transportation zone of a tubular reactor, optionally equipped with a water removal system, in the presence of at least one poly(alkylene glycol) in solid or molten form and of an antioxidant, said esterification and/or amidification taking place at a temperature greater than or equal to 170° C.
