Title:
熱固定化ポリサッカライド誘導体
Document Type and Number:
Japanese Patent JP4275737
Kind Code:
B2
Abstract:
The invention essentially relates to thermally crosslinked polysaccharide derivatives which contained no polymerizable functional groups prior to crosslinking and which are used in particular as support materials for the chromatographic separation of enantiomers. The present invention relates to thermally crosslinked polysaccharide derivatives in which the OH groups, as OR groups, have been esterified or converted into a carbamate (urethane), or mixtures of these, with the proviso that the OR groups contained no polymerizable double bonds prior to crosslinking. The thermally crosslinked polysaccharides according to the invention in conditioned form can also be used as pure polymers for the chromatographic separation of enantiomers.
