摘要： A method and composition for controlling tartar formation in the mouth is reported based upon low molecular weight polymers. These polymers are formed from a mixture of mono- and di- carboxylic vinyl monomers reacted with hypophosphite groups. Particularly effective are phosphorus containing acrylate/maleate polymers of weight averaged molecular weight ranging from about 400 to 5000.
