The invention relates to coated seeds of certain plant species, the seeds having a coating for improving the efficiency of phosphorus in the plant nutrients during the early growth of the plant, the coating comprising : i an aqueous fixing agent which contains a fluid byproduct of agriculture or fermentation and possibly an emulsified oil, and ii a fertilizer powder which, depending on the plant species, is monopotassium phosphate, monocalcium phosphate, dicalcium phosphate, or urea phosphate.

本发明涉及某些植物品种的包衣种子，所述种子具有能提高植物生长的早期阶段的植物营养物中的磷效率的包衣，所述包衣含：i含农业或发酵的流体副产品和可能含有的乳化油的含水固定剂，和ii肥料粉末，所述肥料粉末根据植物品种是磷酸二氢钾、磷酸一钙、磷酸二钙或磷酸尿素。

In this report, half-esterification between these pendent hydroxyl groups of hydroxyl-PU and maleic anhydride could lead to new pendent groups, carboxylic groups. These highly polar carboxylic groups in the side chain of PU could play the role of internal emulsifier. They had self-dissociation ability in the water or were neutralized first by appropriate amount of base. Then, PU bearing carboxylic group could dispersed steadily in the water, named aqueous-based polyurethane dispersion.

在本论文中，利用原来亲油性Hydroxyl PU主链段上悬挂的羟基经由与琥珀酸酐的半酯化(Half-esterification Reaction)反应后，使PU在侧链上悬挂具有强极性的羧酸基，其可作为聚胺酯分子中的内乳化剂，羧酸基能在水相中自身解离产生离子或加入适量碱使之中合，使聚氨酯高分子能够稳定分散於水中，即所谓水性PU分散液(Aqueous-based Polyurethane Dispersion)。
