主权项 1. A polyurethane dispersion comprising: one or more polyurethane units derived from one or more prepolymers, wherein said one or more prepolymers comprise the reaction product of soybean oil based polyols having a hydroxyl number below about 100 mg KOH/g, a substance selected from the group consisting of dimethylol propionic acid, dimethylol botanic acid and diaminosulfonate, and one or more isocyanates in an organic solvent; and water wherein the soybean oil based polyols are prepared from soybean oil in a process comprising epoxidation, hydroxylation, ozonolysis, esterification, hydroformylation and/or alkoxylation, and wherein the organic solvent is selected from the group consisting of dipropylene glycol dimethyl ether, tripropylene glycol dimethyl ether, acetone, methyl ethyl ketone, toluene, tetrahydrofuran (THF), propylene glycol methyl ether acetate, dipropylene glycol methyl ether acetate, propylene glycol diacetate, diethylene glycol n-butyl ether acetate, and ethylene glycol n-butyl ether acetate.
