PCT No. PCT/SE94/01090 Sec. 371 Date Jul. 8, 1996 Sec. 102(e) Date Jul. 8, 1996 PCT Filed Nov. 17, 1994 PCT Pub. No. WO95/13861 PCT Pub. Date May 26, 1995The present invention is directed towards a separation method comprising the steps: (i) contacting an aqueous liquid that contains a dissolved substance that is to be enriched with a polymer under conditions allowing selective partition of said substance to said polymer, whereafter (ii) said polymer containing said substance is removed from said aqueous liquid. The polymer employed is a poly(vinyl ether) having different or identical vinyl ether subunits (1) where X et Y are selected among hydrogen and methyl; and R is selected among organic groups. A plurality of R are equal to a hydrophilic organic group. One or more R comprise a bioaffinity ligand; an ion exchange group, etc. The method may be applied to bioseparations such as gel, affinity, ion exchange and covalent chromatography and corresponding batch procedures. Also disclosed are vinyl ether polymers that can be employed in the method. |
