The process for the controlled radical (co)polymerization of (meth)acrylic and/or vinyl monomers is characterized in that the bulk, solution, emulsion or suspension polymerization or copolymerization is carried out, at a temperature at which can fall to 0 DEG C., of at least one of the said monomers in the presence of an initiating system comprising a radical-generating compound and at least one catalyst composed of a metal complex containing a ligand of the type[4-R3-2,6-(CH2NR1R2)2C6H2]-(I)in which: R1 and R2, which are identical or different, represent a branched or unbranched C1-C4 alkyl group or a phenyl group or alternatively R1 and R2 form, with the nitrogen atom to which they are connected, a cyclic amine or alternatively the two R2 groups, taken together, form a polymethylene bridge and R3 represents a hydrogen atom, an alkyl or benzyl group or an electron-donating or electron-withdrawing functional group.
