ABSTRACT:
The present invention relates to the technical sector of the polymerisation of acrylic acid and its salts, more particularly in solution, more particularly by controlled radical method, the use of the corresponding organo-sulphurated transfer agents, the acrylic acid polymers thus obtained, having a very low polydispersity PD (or very low polymolecularity index IP, which is an equivalent term), and their applications in industry.
