    摘要： The invention concerns a method for preparing a direct emulsion, which consists in diluting in an aqueous phase a clear emulsifiable concentrate comprising an oil phase, optionally water, and amphiphilic compounds consisting of at least one surfactant, at least one copolymer having at least one hydrophilic segment and at least one hydrophobic segment, optionally at least one co-surfactant and optionally at least one neutralizing agent; the total content in amphiphilic compounds representing 1 to 40 wt. % of the emulsifiable concentrate; the copolymer content representing at least 0,1 to 25 wt. % of said amphiphilic compounds; more than 75 wt. % of the emulsion droplets have an average size not more than 1 m; the average size of the droplets of an emulsion obtained by diluting a emulsifiable concentrate free of said copolymer; the total concentration in amphiphilic compounds being the same in both cases.

    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).
