Title:

PHOTOCHEMICALLY CROSS-LINKED POLYSACCHARIDE DERIVATIVES HAVING NO PHOTOPOLYMERISABLE FUNCTIONAL GROUP

Document Type and Number:

Japanese Patent JP2008081745

Kind Code:

A

Abstract:

To provide photochemically cross-linked polysaccharide derivatives that do not contain photopolymerisable functional group prior to the cross-linking, which can be substantially used as a carrier material for chromatographic separation of enantiomers.

In the photochemically cross-linked polysaccharide derivatives, OH groups as OR groups have been esterified or converted into carbamate (urethane) or mixtures thereof, with the proviso that OR groups do not contain polymerisable double bonds prior to the cross-linking.
