(EN) A Process for the preparation of a copolymer comprising sequences of alternating monomer residues, which process comprises reacting at least one donor monomer with at least one acceptor monomer in the presence of: 1) a transition metal complex comprising at least one (Alpha)-acid ligand; 2) an organic compound, which may be a polymer, comprising at least one carbon-halogen bond, an acetylenic bond or an ethylenic bond conjugated with one or more electron attracting (-R) groups; and 3) a Lewis acid. (FR) Procede de preparation d'un copolymere comprenant des sequences de restes monomeres alternes, ce procede se basant sur la reaction entre au moins un monomere donneur et un monomere accepteur en presence de: (i) un complexe de metal de transition comprenant au moins un groupe de coordination (Alpha)-acide; (ii) un compose organique, qui peut etre un polymere, comprenant au moins une liaison carbone-halogene, une liaison acetylenique ou une liaison ethylenique conjuguee avec un ou plusieurs groupes d'attraction d'electrons (-R); et (iii) un acide de Lewis.
