Abstract
Novel polyanionic polymers including families of repeat units, such as maleic, itaconic, and sulfonate repeat units. The polymers are at least tetrapolymers and may be in the acid form or as partial or complete salts. The polymers may be synthesized using free radical initiators in the presence of vanadium compounds. The polymers have a variety of uses, particularly in agricultural contexts.
