Abstract: The present invention relates to a process for polymerizing ethylene-1-butene copolymers in a solution polymerization process by firstly modelling polymer systems for solution polymerization of ethylene-1-butene copolymers and then transferring pressure and temperature conditions from said modelled polymer systems to a solution polymerization process to ensure that the polymerized ethylene- 1-butene copolymer is completely solved in the solvent during the polymerization process.
