摘要： Process of polymerization comprises radical polymerization of the monomer in mini-emulsion, micro-emulsion or emulsion in the presence of at least one water-soluble alkoxyamine. A polymerization process comprises radical polymerization of the monomer in mini-emulsion, micro-emulsion or emulsion in the presence of at least one water-soluble alkoxyamine of formula (I). R 11-3C alkyl; and R 2alkaline metal such as Li, Na or K, or ammonium ion such as NH 4 +>, NBu 4 +> or NHBu 3 +>. Independent claims are also included for: (1) preparation of multiblock polymers comprising preparing a first block, introducing a second monomer or a mixture of monomers-different from the first block without stopping the agitation, without recooling or other interruption, and optionally introducing a monomer or a mixture of monomers different from the second block (where the polymer blocks are constituted based on the nature of the monomers); (2) polymer particle comprising a polymer obtained by the process; and (3) a latex comprising a group of particles.
