Abstract
A method for the separation of a predetermined compound comprising i) partitioning the compound in a two-phase (system A) in which at least one of the phases is rich (phase ) and the other is poor (phase ) in a thermoseparating polymer (I), ii) collecting one phase (phase or phase ) containing said compound, and iii if desired, further working up said compound from the phase collected in step ii, characterized a) in that polymer (I) is a micell-forming thermoseparating polymer, and b) in that phase possibly contains at least one agent that is cloud point-decreasing for thermoseparating polymer (I), such as a polymer (II) that is incompatible with polymer (I) or a salt.
