Title:
光重合性官能基を持たない光化学的に架橋した多糖類誘導体類
Document Type and Number:
Japanese Patent JP5079459
Kind Code:
B2
Abstract:
The invention relates to substantially photochemically cross-linked polysaccharide derivatives that do not contain photopolymerisable functional groups prior to the cross-linking, which can be used as carrier materials for the chromatographic separation of enantiomers. The present invention relates to photochemically cross-linked polysaccharide derivatives in which the 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 prior to the cross-linking. The photochemically cross-linked polysaccharides according to the invention in conditioned form can also be used as pure polymer for the chromatographic separation of enantiomers.
