Abstract:
A method of separating a poly(arylene ether) from a solvent includes treating a poly(arylene ether)-containing solution with a devolatilizing extruder to form an extruded composition, and cooling the extruded composition with a cooling device that does not immerse the extruded composition in water. The composition may be used to isolate a poly(arylene ether) from the solvent-containing reaction mixture in which it is prepared, or to remove solvent from a multi-component poly(arylene ether)-containing thermoplastic composition.
