New amphiphilic poly(vinylsaccharide)s (poly( 7 ) and poly( 8 )) were synthesized. Various alkylamino substituted mono‐ and disaccharides 3 and 5 were obtained by reductive amination of reducing mono‐ and disaccharides with alkylamines. The reaction of these monofunctionalized sugar derivates with 2‐isocyanatoethyl methacrylate ( 2 ) leads to well‐defined monomers ( 7 and 8 ) of the urea type. The monomers were polymerized in aqueous solution to high‐molecular‐weight polymers, using the redox initiator system (NH 4 ) 2 S 2 O 8 /Na 2 S 2 O 5 . The influence of structural variations by changing the hydrophilic sugar moiety or the lipophilic alkyl part was studied by viscometry, light scattering and measurements of the surface tension.
