  • Block copolymers of polysaccharides and polyalkylene oxides
    Patent number: 5490978
    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.

  • Phosphorylated polyhydroxy compounds for tartar control
    Patent number: 5202111
    Abstract: A composition and method for controlling tartar formation in the mouth is reported based upon phosphorylated polyhydroxy substances. These substances are formed by phosphorylation of a polyhydroxy starting compound of molecular weight no higher than 5000, have a molar substitution of at least 2 based on molecular weight of an average repeat unit in the starting polyhydroxy compound and possess phosphate ester linkages satisfying at least one criteria selected from:(a) at least one multi-substituted phosphate ester linked through an oxygen atom to a single carbon of the polyhydroxy compound; and(b) at least two monophosphate groups separated by no more than three carbon atoms.
