Title:

ANIONIC POLYMERS COMPOSED OF DICARBOXYLIC ACIDS AND USES THEREOF

Document Type and Number:

WIPO Patent Application WO2002071086

Kind Code:

A8

Abstract:

Biodegradable anionic polymers are disclosed which include recurring polymeric subunits preferably made up of dicarboxylic monomers such as maleic anhydride, itaconic anhydride or citraconic anhydride. Free radical polymerization is used in the synthesis of the polymers. The polymers may be complexed with ions and/or mixed with fertilizers or seeds to yield agriculturally useful compositions. The preferred products of the invention may be applied foliarly or to the earth adjacent growing plants in order to enhance nutrient uptake by the plants.
