The heated solution is passed to a separation el step, which is conducted at a pressure of no more than 15 bar and in which separation step a liquid phase comprising the polymer 0 and a vapour phase coexist. A vapour stream and a concentrated solution stream comprising the polymer are withdrawn from the separation step. At least a part of the vapour stream is passed to the first polymerisation reactor, to the second polymerisation reactor 5 or to both.
