Abstract:
1. A plant for the continuous solution polymerization of one or more olefin monomers, the plant comprising: a primary reactor and a secondary reactor arranged to operate in parallel, the ratio of the internal volume of the primary reactor to the internal volume of the secondary reactor being in the range of from 60:40 to 95:5; a primary feed line for supplying a primary feed comprising one or more olefin monomers in a solvent to the primary reactor, and a primary catalyst supply apparatus for supplying a first polymerization catalyst to the primary reactor, to form a primary polymer-containing polymerization reaction mixture therein; a secondary feed line for supplying a secondary feed comprising one or more olefin monomers in a solvent to the secondary reactor, and a secondary catalyst supply apparatus for supplying a secondary polymerization catalyst to the secondary reactor, to form a secondary polymer-containing polymerization reaction mixture therein; a junction for combining the primary and secondary polymer-containing polymerization reaction mixtures downstream of the primary and secondary reactors to form a combined polymerization reaction mixture, and at least one separator for isolating polymer from the combined polymerization reaction mixture.
