C. and fed to a plug-flow agitated tubular reactor, which is divided into several stages or zones. The excess mixture is recycled to the premixer and the remaining part of the diluent solvent is injected into the top of the reactor to prevent the formation of incrustations. In the first zone of the reactor, the temperature and the residence time of the mixture are regulated so to have the halving the catalyst life.The polymerization is carried on in the following zones of the reactor until at least the 40% by weight of solids and it is eventually brought to conclusion in one or more consecutive tubular reactors like the first one.
