Dextran, a neutral bacterial polysaccharide, is chemically modified by reaction with an aromatic epoxide (phenylglycidylether). The reaction conditions are either homogeneous, using dimethylsulfoxide as a common solvent, or heterogeneous, dispersing the epoxide into an aqueous solution of dextran. The grafting yield is much higher in homogeneous conditions. The viscometric characteristics of the amphiphilic polysaccharides are examined in water and in dimethylsulfoxide. These properties clearly… CONTINUE READING
