Process for controlled free-radical polymerization of acrylic acid and salts thereof, obtained polymers with low polydispersity and their use

摘要

The invention concerns the technical field of polymerisation of acrylic acid and its salts, more particularly in solution, more particularly controlled free-radical polymerisation, the use of corresponding organo-sulphur transfer agents, the resulting acrylic acid polymers, having very low polydispersity (or very low polymolecularity index, which is equivalent in meaning), and their industrial uses.
