Procedure
H2O: A slurry of D,L-Asn.H2O (500 mg) and poly-(Nε -methacryloyl-L-lysine) in water (5 ml) was heated to about 80° C. until complete dissolution occurred. The warm solution was filtered and cooled to room temperature without agitation. After 20 h the separated crystals were recovered by filtration and the enantiomeric excess was determined. The conditions and results are summarized in Table III.
