Block copolymers of polysaccharides and polyalkylene oxides

Abstract

Polysaccharides (e.g., dextran) of different molecular weights were substituted at the anomeric carbon with polyalkylene oxides of different molecular weights to give novel diblock copolymers. The copolymers inhibit bacterial aggregation. The copolymers are useful as antiplaque agents, as agents to prevent bacterial aggregation in an aqueous system or in a fermentation system.
