Plants and processes for forming polymers

摘要

The present invention relates to a process of forming a polymer, the process comprising polymerizing olefin monomers to form a reaction mixture, treating the reaction mixture to form a first polymer-rich phase, treating the first polymer-rich phase to form a second polymer-rich phase, and devolatilizing the second polymer-rich phase, the process further comprising at least one step of adjusting the temperature of a first and/or the second polymer-rich phase before the devolatilization. The present invention also relates to a plant that is useful for the process provided above.

主权项

1. A process of forming a polymer comprising the steps of:
(a) supplying a feed having one or more olefin monomers and a solvent; (b) contacting the feed with a catalyst to form a reaction mixture; (c) treating the reaction mixture to form a first polymer-rich phase; (d) treating the first polymer-rich phase to form a second polymer-rich phase; (e) devolatilizing the second polymer-rich phase to obtain the polymer, and (x) adjusting between step (c) and step (e) the temperature of the first or the second polymer-rich phase.
