摘要: The invention relates to substantially photochemically or thermally cross-linked polysaccharide derivatives in which the OH groups as OR have been esterified converted into carbamate (urethane) mixtures thereof and that do not contain photopolymerisable functional prior cross-linking. They can be used carrier materials for chromatographic separation of enantiomers.
