Abstract

A process for polymerizing ethylene .alpha.-olefin and optionally diene monomers is disclosed. The process comprises the steps of contacting: (1) ethylene, (2) at least one C3-C20 aliphatic .alpha.-olefin, (3) optionally, at least one C4-C20 diene, (4) a catalyst, the catalyst comprising (a) a metallocene complex, and (b) an activator, and (5) a solvent.
The process can be conducted in a single or multiple reactors, and if in multiple reactors, then the reactors can be configured in series or parallel. Solvent is removed from the polymer stream in an anhydrous, first stage solvent recovery operation such that the solids concentration of the product stream is increased by at least 100 percent.
Additional solvent is removed in an anhydrous, second stage solvent recovery operation from the product of the first stage solvent recovery operation such that the solids concentration of the product stream is in excess of 65 weight percent.
