Abstract: Polymers imprinted with sucrose and corresponding non-imprinted polymers are prepared photo-chemically at 3á¦C and thermally at 65á¦C. The pre-polymerization complex formation in dimethyl sulfoxide between sucrose and methacrylic acid via hydrogen bonding was investigated through 1H NMR titration. The imprinting effect and the selectivity of the imprinted polymers in water are studied by batch rebinding studies with different mono and disaccharides and fitted to the Freundlich isotherm. Based on the calculated numbers of binding sites and average affinity, it is concluded that sucrose has been successfully imprinted at 3 and 65á¦C. The polymer imprinted at 3á¦C possesses the best recognition properties. The imprinted polymers are selective towards sucrose in water
