Abstract

This invention concerns a method for preparation of poly(meth)acrylate composition, in which ethylenically unsaturated monomers are polymerized by means of initiators that have a transferable atomic group, and one or more catalysts that include at least one transition metal, in the presence of ligands that can form a coordination compound with the metallic catalyst(s) to form polymers, where ethylenically unsaturated monomers that contain 50-100 wt %, with respect to the total weight of the ethylenically unsaturated monomers, (meth)acrylates of formula (I) where R means hydrogen or methyl, R1 means a linear or branched alkyl residue with 6-40 carbon atoms, R2 and R3 independently mean hydrogen or a group of the formula—COOR′, where R′ is hydrogen or a linear or branched alkyl residue with 6-40 carbon atoms, is polymerized in the presence of 5-95 wt % mineral oil, with respect to the total weight of the composition.
