ABSTRACT:
A novel, highly water soluble complex of a substantially insoluble organic compound and a solid homopolymer or copolymer of N-vinyl-2-pyrrolidone. The complex exhibits water solubilities in excess of about 25-fold that of the insoluble organic compound. A method for producing the complex is disclosed wherein the polymer and insoluble compound are dissolved in a mutual solvent, allowed to react for a period of time sufficient to form the complex, and then the solvent is removed to produce the dried highly water-soluble complex.
