This invention concerns a method for preparation of a liquid polymer composition, where ethylenically unsaturated monomers are polymerized by means of initiators that have a transferable atomic group, and one or more catalysts that contain at least one transition metal, in the presence of ligands that can form a coordination compound with the metallic catalyst(s), the catalyst is oxidized after the polymerization and then the catalyst is separated by filtration, where the composition contains a solvent with a dielectric constant less than or equal to 4. |
