Title:
アニオン性ビニル/ジカルボン酸ポリマーとその用途
Document Type and Number:
Japanese Patent JP2004515561
Kind Code:
A
Abstract:
Biodegradable anionic polymers are disclosed which include recurring polymeric subunits preferably made up of vinylic and dicarboxylic monomers such as maleic anhydride, itaconic anhydride or citraconic anhydride, or combinations thereof. Free radical polymerization is used in the synthesis of the polymers, which are then hydrolyzed to replace ester groups with alcohol groups. The polymers may be complexed with ions and/or mixed with fertilizers or seed to yield agriculturally useful compositions. The preferred products of the invention may be applied foliarly, to seeds, to fertilizer, or to the earth adjacent growing plants in order to enhance nutrient uptake by the plants.
