Abstract
A method for increasing the water-solubility of highly insoluble organic compounds by forming a novel complex product from the reaction between the organic compound and an oligomer of vinylpyrrolidone. The complex is highly stable and results in solubilities of the organic compounds in excess of 25-fold.
