    摘要: What is described herein is a PVP-I.sub.2 composition comprising strongly swellable, lightly crosslinked PVP complex to iodine, wherein said composition is capable of releasing free iodine slowly with time in the presence of water. Preferably the complex has about 10-15% by weight available iodine and about 4-8 weight % iodide, and is a free-flowing, fine, lightly yellow powder.
