ABSTRACT:
Polymers are disclosed that are useful in performing chiral separations. A synthetic scheme for producing the novel polymers is also disclosed. The alkyl side chains of poly(.gamma.-alkyl-.alpha.,L-glutamates) have been altered, allowing the facile substitution of the side chains with pendent functional groups. The compounds may be used as a stationary-phase or pseudo-stationary phase in separation techniques such as high performance liquid chromatography, or electrokinetic capillary chromatography. The novel compounds are water-soluble or water-swellable, and are particularly useful in separations of stereoisomers.
