Photochemically crosslinked polysaccharide derivatives which have no polymerizable functional groups.

The invention relates to derivatives photochemically crosslinked polysaccharide SUBSTANTIALLY WITHOUT FUNCTIONAL GROUPS NO PRIOR TO photopolymerizable Crisscross, WHICH CAN BE USED AS MATERIALS FOR VEHICLE Chromatographic separation of enantiomers. The invention herein refers to Polysaccharide Crosslinked photochemically WHERE OH groups as OR groups have been esterified or converted into carbamate (urethane) or mixtures thereof, with the proviso that the OR groups do not contain polymerisable double bonds BEFORE crisscross. Crosslinked Polysaccharide photochemically IN ACCORDANCE WITH CONDITIONED invention as CAN BE USED AS PURE POLYMER FOR Chromatographic separation of enantiomers.
