    Abstract: The invention relates to a method for the production of iodine polyvinylpyrrolidone in an aqueous solution, whereby an aqueous polyvinylpyrrolidone solution and at least 4.0 wt % of elemental iodine, in relation to the calculated solid content of polyvinylpyrrolidone, are mixed. The said invention is characterized in that at the time of mixing the concentration c of the aqueous polyvinylpyrrolidone solution, in relation to the total amount of polyvinylpyrrolidone and water, and the K-value of polyvinylpyrrolidone, have the following relationship: c > 100 x [0.1 + 8: (K + 5)] whereby c is given in wt % and the K-value according to Fikentscher ranges from 10 to 100. The invention also relates iodine polyvinylpyrrolidone solutions which are obtained according to said method. Solid iodine polyvinylpyrrolidone can be obtained after removal of water and other volatile components from an iodine polyvinylpyrrolidone solution. The invention further to the use of aqueous iodine polyvinylpyrrolidone solutions containing dissolved solid iodine polyvinylpyrrolidone for the production of disinfectants, weak disinfectants or for the treatment of wounds and for the production of wound coverings.
