| abstract |
Biodegradable anions containing recurring polymeric subunits preferably composed of vinyl and carboxylic acid monomers such as vinyl acetate or vinyl alcohol and maleic anhydride, itaconic anhydride or citraconic anhydride, or a combination thereof Disclosed is a polymer. The polymer is synthesized using free group polymerization and then hydrolyzed to replace the ester group with an alcohol group. The polymer is complexed by ions and / or mixed with fertilizers or seeds to form agriculturally useful compositions. Preferred products of the invention are sprayed onto foliar, seed, fertilizer, or soil adjacent to growing plants to enhance nutrient uptake by the plant. |
