<p>A method for controlled radical (co)polymerisation of (meth)acrylic and/or vinyl monomers comprises (co)polymerisation in mass, solution, emulsion, or suspension at a temperature which can go as low as 0 degrees C. The method is carried out in the presence of a primer comprising at least one radical generator; and at least one catalyst consisting of metal complex of formula MAa(L)n (I), where M = Fe, Ru, or Os; A = halogen or pseudo-halogen; L = (chiral) ligand, selected from PRR'R", P(OR)(OR')(OR"), NRR'R", ORR', SRR', SeRR', AsRR'R", and SbRR'R"; R, R', R" = 1-14C (substituted) alkyl or (substituted) aromatic, at least two ligands being linked by one or more bivalent radicals; a = 1-3; and n = 1-3. The method also requires the absence of activators; systems such as 1-phenyethylchloride/RuCl2 - PPh3, and benzyl chloride/FeCl2 - (Et))3P being excluded in the polymerisation of styrene.</p> |
