摘要:
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.
摘要(中):
公开了可生物降解的阴离子聚合物,其包括优选由二羧酸单体如马来酸酐,衣康酸酐或柠康酸酐组成的重复的聚合物亚单位。 自由基聚合用于聚合物的合成。 聚合物可以与离子络合和/或与肥料或种子混合以产生农业上有用的组合物。 本发明的优选产品可以叶面施用或邻近生长植物的土壤,以增强植物的营养吸收。
