    • The invention relates to a polycarboxylate-type polymer dispersant comprising at least one copolymer which is obtained from a composition of monomers containing, in moles: A) 40 to 95 % of at least one unsaturated carboxylic monomer; B) 5 to 60 % of at least one acrylic or methacrylic ester monomer containing a polyether chain; and C) 0 to 20 % of at least a third monomer which is selected from acrylic ester or methacrylic ester or acrylamide or a derivative of acrylamide or aromatic vinyl monomer or the sulphonated derivative thereof. According to the invention, the copolymer has a controlled molecular mass distribution and can be obtained using a method comprising the following steps: i) polymerisation in aqueous solution at a temperature varying between 70 and 95 °C with a priming and transfer system comprising D) an oxidising agent and E) a reducing agent which is selected from metabisulphite salts, preferably sodium or potassium metabisulphite, the monomer/reducer molar ratio not exceeding 50; ii) semi-continuous addition of the oxidant and the monomer mixture over a time of between 1 and 4 hours; and (iii) introduction of the reducer which can be introduced as a starter before the addition of the oxidant and the monomers, semi-continuously and mixed with the monomers, or semi-continuously but supplied separately from the monomers and the oxidant. The invention also relates to a specific preparation method and to the uses thereof as a fluidising agent in mineral hydraulic binder compositions or as a dispersant agent in pigment pastes or aqueous polymer dispersions.
