摘要： The present invention relates to a method for preparing a polymer based on N-vinyl lactam monomer units, which comprises a step (E) for controlled radical polymerization of a composition comprising: monomers containing (and most often consisting of) N-vinyl lactam monomers, either identical or different (and generally identical); an agent for controlling the radical polymerization, for example comprising a thiocarbonylthio group —S(C═S)—; and a radical polymerization initiator which is a redox system comprising a reducing agent (Red) and an oxidizing agent (Ox).
