ABSTRACT:
A process for efficiently utilizing hypophosphorous acid or salts thereof as a chain transfer agent is provided wherein the polymerization is conducted to a final polymer solids level of at least about 50 percent by weight.
The polymers produced are useful as dispersants for paint formulations, additives for laundry and machine dishwashing detergents, mineral dispersants, dispersants for kaolin clay slurries and scale inhibitors, dispersants and corrosion inhibitors for water treatment and oil production.
