This process is characterized by the fact that one polymerizes or copolymerizes in mass, solution, emulsion or suspension, at a temperature which can drop to 0 ° C., at least one of said monomers in the presence of a starting system. comprising at least one radical generating compound other than arene sulfonyl chloride; and at least one catalyst consisting of a metal complex represented by the following formula (I): MAa (L) n in which: M represents Ni, Pd or Pt; A represents a halogen or a pseudohalide; the Ls are ligands of the metal M, independently chosen from those containing at least one from N, P, As, Sb, Bi, at least two of these ligands possibly being linked together by one or more divalent radicals; a is an integer of 0 to 5, with the proviso that, when M is palladium, a is other than 0; n is an integer of 1 to 4; with 4 = <a + n = <6, a + n representing the coordination number of the complex. |
