PCT No. PCT/SE92/00878 Sec. 371 Date Sep. 12, 1994 Sec. 102(e) Date Sep. 12, 1994 PCT Filed Dec. 18, 1992 PCT Pub. No. WO93/13034 PCT Pub. Date Jul. 8, 1993A process for separating a selected amino acid (enantiomer) from a mixture of different compounds including other amino acids is disclosed, in which process the mixture is contacted with a polymer material which is composed of cross-linked, amino-acid-based monomer units, said polymer material containing a molecular print of the selected amino acid. In the molecular print there is also bound a diastereomeric complex between the selected amino acid (enantiomer), a divalent metallic ion and the amino-acid-based monomer unit. Also the amino-acid-based monomer unit and a process for preparation thereof, as well as a polymer material composed of the amino-acid-based monomer unit and a process for the preparation thereof are disclosed. |
