Polysaccharide derivatives coating onto silica matrices represent nowadays one of the most popular chiral stationary phases (CSPs) and these kinds of phases are commercially available. However, the solubility of polysaccharide derivatives in a number of solvents limits the application range on the commercial chiral columns. This problem can be solved by chemically fixing polysaccharide derivatives onto silica matrices. Chemically bonded-type CSPs already have been prepared by radical polymerization, radical co-polymerization reaction, and etc. method by many researchers. In this study, we prepared cellulose phenyl carbamate derivatives-grafted silica particles from cellulose 2,3-bis(3,5-dichlorophenylcarbamate)-6-methacrylate and the initiator-grafted silica particle, which is synthesized from aminated silica gel (5 μm, 1000Å) and 2-bromoisobutyryl bromide, by atom transfer radical polymerization. |
