Abstract

In at least one embodiment, a process of forming a polymer includes supplying a feed having one or more olefin monomers and a solvent; contacting the feed with a catalyst to form a reaction mixture; treating the reaction mixture in a first separator to form a first polymer-rich mixture; introducing the first polymer-rich mixture into a second separator; introducing a volatile component and/or inert component into the first separator, the second separator and/or a line between the first separator and the second separator; treating the first polymer-rich mixture to form a second polymer-rich mixture; and devolatilizing the second polymer-rich mixture to obtain the polymer.
