Abstract
The invention relates to the preparation of a water-soluble anionic polymer, the weight-average molecular mass Mof which ranges from 1,000 to 10,000 g/mol and the polydispersity index Iof which is less than 3.5. The polymer according to the invention is obtained by a polymerization reaction in water of an unsaturated anionic monomer, in the presence of Cuor of Cuand of an aromatic compound comprising a functional group chosen from hydroxyl, primary amine, secondary amine and tertiary amine directly bonded to the aromatic ring. The invention also relates to an aqueous composition comprising the polymer according to the invention.
