    摘要: Polyvinylpyrrolidone-iodine, manufactured by reaction of iodine and a polyvinylpyrrolidone obtained by polymerization in an anhydrous organic solvent in the presence of a source of free radicals and optionally in the presence of a heavy metal of atomic number from 23 to 29, in the form of a complex compound or of a salt with an organic acid, as a co-activator, followed by steam distillation of this polyvinylpyrrolidone, if appropriate. The PVP-iodine of the invention is very stable and can be used as a disinfectant.
