POLYVINYLPYRROLIDONE-IODIDE COMPOSITIONS AND POLYVINYLPYRROLIDONE-IODIDE-IODINE COMPLEXES PREPARED THEREFROM

摘要

A unique PVP-iodide solid solution is prepared by drying a solution of PVP and iodide wherein the PVP:I- ratio is preferably in the range of about 2:1 to 6:1, which dried product may then be mechanically blended with elemental iodine at ambient temperature to rapidly form a stabilized PVP-iodide-iodine complex, characterized in that the resulting product comprises a single solid phase.
