Abstract:
A method for preparation of a poly(meth)acrylate compositions, in which 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), wherein ethylenically unsaturated monomers that contain 50-100 wt %, with respect to the total weight of the ethylenically unsaturated monomers, of one or more ethylenically unsaturated ester compound of formula (I) where R is 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 â€”COORâ€², where Râ€² is hydrogen or a linear or branched alkyl residue with 6-40 carbon atoms, are polymerized in the presence of 5-95 wt % mineral oil, with respect to the total weight of the composition.
