In a process for the production of poly(meth)acrylate compositions by polymerisation of unsaturated monomers in presence of initiators, transition metal catalysts and coordinating ligands, polymerisation is carried out in presence of a mineral oil using a monomer mixture comprising 50-100 wt% unsaturated ester compounds. A process for the production of poly-(meth)acrylate compositions involves polymerisation of ethylenically unsaturated monomers with the aid of initiator(s) with a transferable atom group and transition metal catalysts(s), in presence of ligands which can form coordination compounds with the catalyst(s). In this process, polymerisation is carried out in presence of 5-95 wt% mineral oil and the monomer mixture comprises 50-100 wt% unsaturated ester compound(s) of formula R 2>R 3>C=CR-COOR 1> (I) in which R : H or methyl; R 1>6-40C alkyl (linear or branched); R 2>, R 3>H or -COOR'; R' : H or 6-40C alkyl An independent claim is also included for a method for the production of polymers by isolating the polymer from a solution obtained by this process. |
