Abstract
A polyurethane composition has particles of solid polyvinylpyrrolidone-iodine complex evenly distributed throughout the polyurethane matrix so that the complex does not associate with the polyurethane to any appreciable extent. In one embodiment of the composition, the polyurethane is thermoplastic for coating or molding applications. In another embodiment, the composition is a polyurethane foam particularly useful as a sponge for scrubbing which provides almost instantaneous release of the complex. The sponge may be provided in a package which includes other items useful for scrubbing.
