Abstract :
[en] A process for a radical-controlled polymerisation or co-polymerisation of (meth)acrylic and/or vinylic monomers is effected en masse, solution, emulsion or suspension at a temperature which may be as low as 0 degrees C, in the presence of a system comprising (i) a radical generator compound other than bromofluorene; and (ii) a catalyst consisting of a Pd complex of degree of oxidation zero, corresponding to formula Pd(0)L<1>L<2>L<3>L<4> (I), where L<1>-L<4> = ligand (possibly chiral) chosen from PRR<1>R<2>, P(OR)(OR<1>)(OR<2>), NRR<1>R<2>, ORR<1>, SRR<1>, SeRR<1>, AsRR<1>R<2> and SbRR<1>R<2>; and R, R<1>, R<2> = 1-14C alkyl (optionally substituted) or aromatic (optionally substituted), at least two of the ligands being capable of interconnecting with one or more bivalent radicals.
