Dextran fractions with a narrow molecular weight distribution were modified using the 4-nitrophenyl chloroformate activation method. The activated polymers were subsequently reacted with a small amount of L- tyrosinamide and a number of selected peracetylated The number of L-tyrosinamide units introduced could be accurately deter mined by UV absorption spectroscopy. On the other hand, the degree of substi tution by a glycoside ligand was calculated from 1H NMR data.
